CORRECTION 1: at, 10:36 it should say: 1 mol = 6.022 * 10^23 (not 10^-23)! CORRECTION 2: 04:20 Generally, salts are formed when acids and bases neutralize. Metals and Nonmetals forming a salt is one possible option, not the general rule. Thanks to the attentive commenters for pointing it out! For people asking about Organic Chemistry…I decided not to include it in this video, as the topic is way too big and deserves a video of its own. …soon, perhaps

2 types of teaching: 1. 17th centuries style 2. This guy

This dude just explained 2 years of chemistry classes in 19 minutes, FOR FREE

Not me watching this video hoping to pass a chemistry exam that I didn't study for

Let's simplify and explore these Chemistry terms ⚛️🧪⚗️: 1. **Isomers/Allotropes:** - Imagine you have a bunch of Legos, and you can rearrange them to make different shapes. (Allotropes are DIFFERENT FORMS of the same element, while Isomers are like molecules REARRANGED to form different structures) For example, Diamonds 💎 and Graphite 🪨 are Allotropes (DIFFERENT FORM) of Carbon, where Diamonds are like tightly packed Legos, while Graphite is like layers of Legos stacked on top of each other in different molecular structures called Isomers (REARRANGED). 2. **Polarized/Non-Polarized Covalent:** -Think of sharing a pizza with a friend. 🍕 -If you both agree ✅ on the same toppings, it's like NON-POLARIZED Covalent Bonding, where Electrons are shared EQUALLY⚡️⚛️🟰. -However, if you both want different toppings and have to compromise ❌, it's like POLARIZED Covalent Bonding, where Electrons are shared UNEQUALLY ⚡️⚛️🤪. 3. **Electronegativity:** - Picture a tug-of-war game, where players compete to pull a rope towards them. 🪢 Electronegativity is like how STRONGLY an atom PULLS electrons towards itself in a chemical bond 💪⚡️⚛️. Elements with high electronegativity are like strong players in the game, pulling the electrons closer to them. 4. **Redox Reaction:** - Imagine playing with a toy car and a battery. When you connect the car to the battery 🏎️🔋, the car moves forward 🏎️💨, but the battery loses energy 🪫. -This exchange of energy 🔀 is called the Redox Reaction, where one substance loses Electrons ➖⚡️⚛️ (Oxidation) and another gains Electrons ➕⚡️⚛️ (Reduction). 5. **Oxidant and Reductant:** - Picture a game of tug-of-war between two teams. 👬🪢👭 The team that pulls the rope towards them is like the OXIDANT, gaining electrons ➕⚡️⚛️, while the team that let’s go of the rope is like the REDUCTANT, losing electrons ➖⚡️⚛️. -Together, they balance each other out in a Redox Reaction ⚖️. 6. **IMFs and Van Der Waals Force:** - Imagine trying to stack books on a wobbly table. 📚🫨 The force that keeps the books together 💪 despite the wobbling 🫨 is like Intermolecular Forces (IMFs) or Van der Waals forces. They're Weak Attractions between molecules that help hold them together, like magnets pulling them closer 🧲. 7. **Surfactants:** - Picture washing dishes with soap. The soap molecules surround grease and dirt., allowing water to wash them away. 🧼🫧 Surfactants are like the soap molecules, with one end attracted to Water 💦 and the other end attracted to Grease 🛢️, helping to remove dirt and oil from surfaces. 8. **Colloid:** - Think of stirring milk in a glass. Even after STIRRING, the milk doesn't fully mix with the water. 🥛❌💧This suspension of tiny particles in a liquid is like a Colloid, where small particles are dispersed but NOT fully dissolved, giving the mixture unique properties. 9. **Stoichiometry:** - Imagine following a recipe 📋 to bake cookies, where you need a specific ratio of ingredients to make the perfect batch 🍪. Stoichiometry is like following a recipe in chemistry 🧪, where you calculate the quantities of reactants and products in a chemical reaction to ensure everything balances out ⚖️. 10. **Enthalpy:** - Picture adding sugar to coffee and feeling the warmth spread throughout the drink 🥵☕️. -Enthalpy is like the TOTAL HEAT CONTENT of a system, including both internal energy and pressure-volume work 📏🔥. It measures the energy exchanged during a chemical or physical process, like adding sugar to coffee and feeling the change in temperature 🌡️. 11. **Exergonic and Endergonic:** -Imagine a roller coaster ride, where some parts go downhill (Exergonic) and RELEASE energy. 🎢⬇️🏔️ 🔥💥 While other parts go uphill (Endergonic) and REQUIRE energy input. 🎢⬆️🏔️ 🔋 -Exergonic reactions are like the DOWNHILL parts ⬇️🏔️, where energy is released Spontaneously 🔥💥. -while Endergonic reactions are like the UPHILL parts ⬆️🏔️, requiring an external energy source to proceed 🔋. -It helps determine whether a reaction is Spontaneous or Non-Spontaneous under specific conditions, like whether a Roller Coaster can make it up a Mountain 🎢🏔️ without any additional energy. 12. **Conjugate and Amphoteric Base:** - Imagine playing with a seesaw, where one side goes up ⬆️ when the other side goes down ⬇️. -A Conjugate base is like the side that goes up when the acid loses a proton ❌💡 while an Amphoteric base is like the seesaw itself, capable of both accepting and donating protons ✅💡depending on the conditions. 13. **Delocalized:** - Think of a group of friends holding hands in a circle, moving around freely. 👫 Delocalized Electrons are like these friends, SPREAD OUT over a large area instead of being confined to one place 🕺 💃 👯‍♀️ They're free to move and participate in chemical reactions. 14. **Orbitals, Electron Configuration, Aufbau Principle:** - Imagine building a tower with blocks, starting from the bottom and stacking them upwards. 🧱🏢 -Electron configuration is like arranging electrons ⚡️⚛️ in specific energy levels (Orbitals) around an atom, following the Aufbau principle. -Orbitals are like the spaces where Electrons are likely to be found around an Atom ⚡️⚛️🧐 while the Aufbau principle is like building the tower 🏗️, filling Orbitals with Electrons from the lowest energy level 🪫 to the highest 🔋 15. **Partial Charge and Dipoles:** -Think of a game where two friends play tug-of-war with a rope. If one friend is stronger 💪, they pull the rope 🪢 towards them ➡️⬅️, creating a Partial Charge. -A Dipole is like this unequal sharing of the rope, where one end becomes slightly positive ➕ and the other slightly negative ➖. -It’s important because it helps molecules interact ⚛️🤝⚛️ with each other, influencing their behavior in chemical reactions and interactions 🧪⚗️. 16. **Plasma:** -Imagine a group of excited dancers at a party 🥳💃🕺, moving energetically and freely. Plasma is like this highly energetic state of matter, where Atoms ⚛️ have been STRIPPED of their Electrons ⚡️⚛️, creating a mixture of positively charged ions and free electrons. -It’s important because it’s the most abundant state of matter in the universe 🌌 and has applications in technologies like plasma TVs and fusion reactors. 17. **Solvent and Solute:** -Picture making lemonade by mixing lemon juice 🍋🥤 (Solute) with water 💦 (Solvent). The water 💦 dissolves the lemon juice 🍋🥤, creating a solution. Solvent is like the “big boss” that does the dissolving 😎, while Solute is like the “guest” that gets dissolved 👔. -To differentiate, remember that Solvent is usually present in larger quantities and DOES the dissolving, while Solute is the substance BEING dissolved. 18. **Conjugate and Amphoteric Base:** - Imagine playing with a seesaw, where one side goes up ⬆️ when the other side goes down ⬇️. -A Conjugate base is like the side that goes up when the acid loses a proton ❌💡 while an Amphoteric base is like the seesaw itself, capable of both accepting and donating protons ✅💡depending on the conditions.

Doing my PhD in chemistry... while watching this video the last 10 years of studying came to mind in time-lapse

Agh. This gave me such horrible flashbacks. I love chemistry, but the schoolish presentation of concepts without practical application gives me a knot of anxiety in my stomach even now. This is an excellent video, honestly, but I wish we taught chemistry differently. Get people in love the practical application of it, and *then* learn the otherwise intangible concepts as doing so becomes necessary to further the application.

dude explained chemistry in 19 min more than my teacher could in 2 years

1. **Charm and Strange Quarks:** • Imagine you have two special friends: one always seems to have a charming personality, 🤩while the other is a bit strange but interesting. 😜 That’s like Charm and Strange quarks. • Charm and Strange quarks are types of elementary particles that are part of the building blocks of protons and neutrons. They’re like the unique characters in the story of particle physics. [These Quarks are important because they contribute to the diversity and stability of matter, influencing how particles interact and form larger structures.] 2. **Gluon:** • Picture a group of friends holding hands tightly, not wanting to let go. That’s like Gluons. • Gluons are particles that “glue” quarks together inside protons, neutrons, and other particles. They’re like the strong bonds that hold everything together. 🤝⚛️ [Gluons are important because they mediate the strong force, one of the four fundamental forces of nature. Understanding gluons helps us grasp the dynamics of nuclear interactions and the stability of matter.] 3. **Hadron:** • Think of a big family gathering with lots of relatives, all coming together to celebrate. That’s like a Hadron. 👨‍👩‍👧‍👦⚛️ • Hadrons are composite particles made up of quarks, such as protons and neutrons. They’re like the extended family of the particle world, formed by combining smaller building blocks. [Hadrons are important because they constitute the majority of visible matter in the universe. They’re crucial for understanding the structure of atomic nuclei and the behavior of matter under extreme conditions.] 4. **Lepton:** • Imagine a group of graceful dancers, each moving elegantly and independently. That’s like Leptons. 👯‍♀️⚛️ • Leptons are a family of elementary particles that includes the electron, muon, and tau, among others. They’re like the solo performers in the particle dance, each with its own unique characteristics. [Leptons are important because they don’t experience the strong nuclear force, making them useful for studying fundamental interactions and particle decays.] 5. **Muon and Tau:** • Think of Muons and Taus as the “heavier” 🏋️‍♂️⚛️ cousins of the electron, each with its own distinctive personality. Muons are like the cool, laid-back cousin 😎, while Taus are the more mysterious and enigmatic ones 🥸. • Muons and Taus are types of Leptons, similar to electrons but with different masses. They’re like the siblings of the electron family, adding diversity to the particle lineup. [Muons and Taus are important because they provide valuable insights into particle physics and high-energy phenomena, such as cosmic ray showers and neutrino interactions.] In summary, Charm, Strange, Gluon, Hadron, Lepton, Muon, and Tau are all important particles in the realm of particle physics and chemistry. 🧪⚛️ Each contributes to our understanding of the fundamental forces and building blocks of the universe, playing essential roles in the structure and behavior of matter at the subatomic level.

Perfect timing! I have exams of chemistry coming up

I've never had the honour to learn this in school because of our classist education system, thank for bringing education to the interested underprivileged! :)

**Fermions:** - Imagine you have a group of particles that are a bit shy and prefer to keep their space. That's like Fermions. 😳⚛️ - Fermions are a type of elementary particle that follow a set of rules called Fermi-Dirac statistics. They're like the individualistic loners of the particle world, always maintaining their own unique identity and space. - Fermions include both matter particles, such as Quarks and Electrons, and Antimatter particles, such as Positrons and Antineutrinos. They're the building blocks of Matter and Antimatter and make up everything we see in the Universe. **Types of Fermions:** 1. **Quarks:** Picture tiny, colorful building blocks, each with its own unique flavor. That's like quarks. - Quarks are fundamental particles that come in 6 types, or "flavors": up, down, charm, strange, top, and bottom. - Quarks are bound together by the strong nuclear force ☢️ to form Protons and Neutrons, which are the building blocks of atomic nuclei. 2. **Leptons:** Imagine a family of particles, each with its own distinct personality and role. That's like leptons. - Leptons include particles like Electrons, Muons, and Taus, as well as their associated Neutrinos. - Leptons are not affected by the strong nuclear force ❌☢️ and exist independently as individual particles. They play a crucial role in various processes, such as beta decay and neutrino interactions. (**Fermionic Properties:** - Fermions obey the Pauli exclusion principle, which states that no two fermions can occupy the same quantum state simultaneously ⚛️❌⚛️. -This property gives rise to the unique structure of matter, with atoms and molecules having distinct energy levels and configurations. - Fermions have half-integer values of spin, which determines their intrinsic angular momentum. 📐 This property distinguishes Fermions from Bosons, which have integer values of spin.) (**Importance and Real-World Applications:** - Fermions are the building blocks of matter and antimatter and are essential for understanding the structure and behavior of the universe at the smallest scales. - They govern the properties of atoms, molecules, and materials, shaping the physical and chemical properties of everything around us. - Fermions have practical applications in various fields, including particle physics, condensed matter physics, and technology. - Understanding Fermions helps scientists develop new materials, technologies, and applications, such as semiconductor devices, superconductors, and quantum computing.) In summary, Fermions are fundamental particles that make up Matter and Antimatter. They include Quarks and Leptons, which are the building blocks of Atoms and Particles. Understanding Fermions is crucial for unraveling the mysteries of the universe and developing new technologies that shape our world.

People with ADHD be thanking you rn. 🗿🗿

I'm a chemical technician by profession and you explained everything perfectly and in a way that's easy to understand, good job!

In Particle Physics ⚛️, "Spin" is a fundamental property of Elementary Particles, like Electrons⚡️⚛️ and Quarks 🔴🔵🟢. Now, imagine you're playing with a spinning top. When the top spins, it has a property called "ANGULAR MOMENTUM" which makes it rotate around an axis 😵‍💫. In particle physics, "Spin" is a bit like that, but it's NOT QUITE the same as physical rotational spinning ❌😵‍💫. 1. **Physical Rotational Spinning:** When you spin a top or a ball 🏈, it physically rotates around an axis. You can SEE IT spinning 👀😵‍💫, and it has a MEASURABLE RATE of rotation. It's like watching a fan blade spin around. 2. **"Spin" in Particle Physics:** Now, let's talk about "Spin" in the particle physics world 😵‍💫⚛️. Imagine you have a tiny ball 🏈, SO TINY you can't even see it 🫥. This "Spin" property ISN’T ABOUT the ball ❌🏈 physically rotating like a spinning top. Instead, it's a FUNDAMENTAL PROPERTY of the particle, kind of like an invisible tag 🫥🏷️ that says how "spinny" the particle is. Think of it like this: Imagine you're playing a game of "spin the bottle," but INSTEAD of a physical bottle spinning around ❌🍾, it's like each player has a HIDDEN TAG 🫥🏷️ that tells you how much "Spin" they have. You CAN’T see the tag ❌👀, but it tells you something important about how the game works. So, in Particle Physics, "Spin" 😵‍💫⚛️ ISN’T ABOUT physical rotation like a spinning top ❌🏈. It's a fundamental property of particles ⚛️ that INFLUENCES how they INTERACT 🤝 with each other and with other forces in the universe 🌌. (One tip is to think of Physical Spinning like something you can SEE 👀 and FEEL 🤚, like a spinning top or a fan blade. "Spin" in Particle Physics 😵‍💫⚛️ is more like an invisible property, a hidden tag 🫥🏷️ that particles have that tells you how much “Spin” they have. “Spin” 😵‍💫⚛️ is also a FUNDAMENTAL PROPERTY of particles that influences how they interact 🤝 with other particles ⚛️ and forces 💪 in the universe 🌌, kind of like a secret superpower!)

Politicians who deny climate change should be forced to summarize what they learned in this video before they are even eligible for office.

This guy deserves more views!!!

When we needed him the most, he returned 🛐 Also please do all of biology too. As a science student this trilogy will save my life

Wonderful explaination!! This is by far one of the most excellent videos briefing high school physical chemistry I've watched.

This man just educated me whole highschool chemistry. Nice work and thanks!

The whole point of chemistry : “ Hey we have got this formula surely we can apply this to all things without any exceptions right?” “ well yes but no”

I love the fast pace format, it is fast enough so you can connect things while also not leaving time for the realization of things you didn't understand to kick in and get you out of the flow zone

I would listen to multiple episodes of this guy explaining things. Please make more chemistry ones.

This is literally the best summary of general chemistry ever created!

2 hours ago I didn't know anything about chemistry. Now, with this video + ChatGPT explanation covering everything I didn't fully understand, I feel fucking powerful

The explanation is just wonderful man, and the humorous 'elements' are just GOLD, love it! ❤

This video is such well made, great work!

Dude, you summed up in 19 minutes what my teacher couldn't in 3 years. Thank you so much for this!

Amazing video! As a teacher I'll definitely be using your videos in class (thanks especially for not adding cuss words). I'm sure you're going to grow into a big channel if you keep producing work like this!

This video is just too good. normally i woulnt do and comments for any kinda video but this is just spectacular. Keep on with what you do, you show some good quality person vibes

Brilliant explanation of all school chemistry! Thank you very!

You have no idea how helpful this is. Been studying for the MCAT and tend to get lost in the sauce of biochem and orgo when I really need a better foundation of chem/phys, and you vids are the perfect speed and concision for me to sort everything out in my head. Excellent work.

1st man to learn everything

Love this type of content actually keeps me interested in the video so i can learn the material definitely recommend

This is great. I feel inspired to get even more chemistry knowledge. Thank you so much

even a top tier video wont be able to convince me that chemistry is something i can handle

I’m a TA for general chemistry and I will absolutely be referring my students to this video- really excellent work!!

Bravo! Cool revision

this was really helpful! thanks for creating it

For the SPDF layer counting, there is an easier method then the chart, you can look at the periodic table and assign each area a letter. Alkaline and Alkaline earth metals(and helium) get S. Post transition metals to noble gasses get P. Transition metals get D. And the Lanthanoid/Actinoid series get the F Block.

As a chemistry major, this made my day! Keep up the good work, I love your videos!

This is tremendously helpful. Thanks for your efforts!

You explained everything faster, while keeping me entertained and keeping it basic while also explaining it in a complicated way. You literally did a better job than three of my chemistry teachers throughout 6 YEARS could.

One of the best videos I had seen in a while.... Deeply researched and man what beautiful concepts you must be having to make such a concise and clear video in such a short time span

*Thanks For The Quick Revision*

Thank you for this valuable insight!!!

I love these vids man. its crazy you only made 6 vids till now

Dude that is a LOT of science in one video and i love it💪🏼

So why school 🏫🎒 teachers keep making us believe Chimestry is hard when in fact the hole topic could easily fit on a 20 mins video full of jokes... 😌 Man school really needs a deep re-thinking 🥱😪

absolutly insane! thanks for that video!

Thankyou so much man! definitely helpful.

Amazing work! You explain complex chemistry concepts so clearly in just 19 minutes! 👍

Just 34k subscribers??? You deserve at least a million for this quality and very good explanation 👏 ❤

Awesome, I learned things I already knew. Now I'm gonna watch again to see if I can learn more of what I already know. Thank you for a wonderful video.

As a chemistry lover and a high school student, I'm impressed of how it did flow so smooth between the subjects. Love it

Uranium is a good alternative to cereal.........

WOW. This channel is AMAZING. I have degrees in math and I think a math video would be FASCINATING!

As someone who is studying chemistry I have to say this a really easy to understand and well put together video, really great work!

This is actually amazing this channel is a gem i hop it succeeds

Really well made video dude. Keep up the amazing work

your timeline must look insane! so many transitions.. i like it

Bro you are awesome, just explained all in just 19 min😮

love the content and delivery, very informative. yet i keep falling asleep half way through. this is my fourth watch through and i realizing my chemistry teacher might have been on to something

So great! You explained everything I learned in the past 5 years in 19 minuets!

genuinely top tier explanation ill comment just to promote it that's awesome, ive sent this too friends as well it's perfect for highschool chem

I must say this is a very good video to fresh up you chemistry knowledge. On top of that, this video explained me how oxidation numbers work in seconds, something I couldnt achieve by myself in multiple hours.

Nice this is everything covered in IB standard level chem (excluding org chem and most formulas). Great vid and a lifesaver.

This guy just told the whole 11th grade

And tomorrow is my physics exam 😶

This was fantastic. Very effective for quick review. Entertaining and held my attention for the entire video. Would be awesome if you did all the MCAT subjects. Subscribed.

extremely useful, thank you ❤

this is amazing my exams start tmrw

I am realy shocked that thing i learned in 3 years can be summed up in 19 minutes 😂

This is so great, i enjoyed this video so much, i think i even might get over my social issues and share it with my chemistry classmates

banger. godsend for revision. thanks mate

Bro revised my highschool chemistry in 19 minutes ☠️

Bruh, you have just cleared some of my doubts that I had for so long. Your videos are awesome.

amazing video. thank you for this!

This was for sure the greatest video I've seen so far this year

Can you do organic chemistry?

bro just explained my whole 9th grade and 10th grade chemistry take my sub

This is the video i have benn searching for. Thanks

From bottom of heart thankyouu so muchh sir for this wonderfull explanation

That's a good revision. Thanks for this video. I am very much satisfied❤

Slight correction: At 15:23, the oxidation numbers are covered Steps 1 and 2 are technically incorrect. 1. H AS AN ION bonded to another atom does (most of the the time) have an ox. number of +1. Such an example would be HF, where the ox. number of H is +1 and F is -1 2. O AS AN ION bonded to another atom has an ox. number of -2. An example is NO3-, where each oxygen atom would have an ox. number of -2 and N would have an ox. number of +5. The reason why H2 and O2 do not act in this way is that they are in their natural state. When not manipulated, a pure solution of H will exist as a gas H2. The same is true about O. Any atom in its NATURAL STATE has an oxidation number of 0.

Awesome job! Loved the Latin bit, you are quite funny but also explained everything nicely.

bro???? where were you back in 2022 WHEN I NEEDED YOU.i still do tho and thank God for been having found this. literally took a periodic properties class the week before and you just explained everything bar hybridization in 19mins instead of fcking 9 hours. bless you

This comment will make you Rich but you'll have to be a millionaire

This dude just covered these chapters 1)Some basic Principles of Chemistry 2)Redox reactions 3)Solutions 4)Thermodynamics 5)Periodic table 6)Atomic Structure 7)Chemical Equilibrium 8)Solid state 9)States Of Matter 10)Chemical Kinetics 11)Chemical Bonding IN JUST 19 MINUTES My three years literally flashed💀 This dude is crazy

This is so useful bro, I study biology and kinda need chemistry for my future major I want to apply to. You explained chemistry more and better than my teacher.

Love the vibe of this video, I will be sticking around 👍

Chipi chipi chapa chpa

This is the best ~19 minutes of chemistry I ever had. I learned how to make a volcano, a slime, and a rainbow in a jar.

wonderful vid, u explained so many things i couldn't understand earlier, thanks

You're videos are really good!!

Lewis theory crying in the corner rn

This is much better than your physics video. You're not a complete copy of Bill Wurtz now! I suggest you further explore your own style! Edit; I again know almost all of this from IB Chemistry HL

Gonna share your vids to some other engineers. I just discovered you and all the videos i saw were super good content. Congratulations

You're a fun teacher. This video moves to quickly for me to really absorb what I don't remember from high school (which is alot), but my curiosity is peaked, and I have good starting places for anything I want to better understand. That's all educators can ask for, sometimes. Good work.

I like the content. Its highly informative understandable and it only explain the key points of the subject. This is can be called as a great example of Pareto principle in my opinion Because it contains the most understandable condensed %20 information that explains most while it keeps the most complicated %80 part out of it. Thanks for the great content keep up.
