World needs teacher's with his skills of making students understand better.

This was explained way better than a teacher or a textbook. Thank you very much.

Rutherford knew very little about alpha particles. He knew they were very small (much smaller than an atom), and he knew they were positively charged. But since he hadn't yet discovered the nucleus, he certainly didn't know that they were actually Helium nuclei!

No teacher would shout "Bam Bam Bam" in the middle of the class😂Hats off to you💯

All great questions! 1) Alpha particles don't actually have to hit a nucleus in order to be moved, because the charges repel 2) If alpha particles were negatively charged, they might stick to the nucleus instead of be repelled by it. 3) I'm sure alpha particles hit electrons, but electrons are so tiny compared to the size of an alpha particle, they don't do anything, it's like a bullet hitting a piece of dust.

Thanks! You know, Ernest Rutherford was from New Zealand. And you should watch my video called "Why Does Everyone Hate Science?" (it's less than a minute long), because there's a subtle New Zealand shout-out in that!

Great question! In order to get repelled by the protons, the alpha particles have to get super close to them (almost touching). And since nuclei are so tiny compared to the atom as a whole, it's really easy for the alpha particle to go through empty space in the atom without coming anywhere near the nucleus.

The world needs teachers like him, he is truly the best.

Niall Horan teaching chemistry. Amazing

8 years later. Still a legend.

I've been watching your videos lately and I just want to thank you so much! I admit that I'm a pretty slow learner, and because of that, I need to take note of every LITTLE DETAIL (it can get quite annoying) just for me to understand a particular lesson. Your conciseness helps out so much and I love how you are able to hold my attention for as long as your videos are! I just want you to know that you are truly amazing and I hope you continue to help other people who are in the same spot as me :) THANK YOU!

Alpha particles are made of only two protons and two neutrons. They are NOT complete Helium atoms; if you want to be precise, they are only the nucleli of Helium atoms, but they don't have any electrons. The nucleus of an atom is tiny compared to the amount of space that a whole atom with electrons takes up, so it's perfectly fair to call an Alpha particle "much smaller than atom," because it is. It's only a tiny piece of an atom.

Thanks for your comment! I hope you'll check out my new website, vespr.org

I've really been enjoying these videos. For the critics, you are entitled to your opinions. However, Tyler has put a lot of effort into his videos, and you can't argue with that. Thank you Tyler.

You had me at your gun imitations. I officially now have a crush on you.

The explanation was honestly the best I had about science. It made me understand the whole model and experiment in just 15 minutes, thank you so much.

You are the best thing that has come out of having to learn chemistry at home during Covid. You make all of this so understandable.

Interesting Nice explanation. I'll share this with my class.

You sir, just saved my life.

Just want to say that I appreciate your videos so much! I've recently started an intro to chemistry course at uni and have been really struggling to get my head around this topic, the way you are explaining things makes it so much easier to understand! Thank You!!

Thank you sooooo MUCH! Chemistry has always been my thing but you are making it a lot more better. I am a proud supporter of your youtube videos. Thanks again!!

These videos are currently and will continue to save my grade this semester. Quickly realizing that I’m a visual learner. THANK YOU!

Very well explained! We need more KZfaq channels and videos like these... keep up the good work

We need more videos from you! You're the best chemistry teacher!

Thank you sir it was nice lecture i am from india watching your videos for our concepts its helps me a lot

It’s so clear and well made, that I don’t have to ask questions to my teacher anymore lol

Making chemistry understandable is extremely hard...You deserve a crazy amount of respect

Thank you Tyler. The mark of a good teacher is their ability to convey information in ways that are understood by those being instructed. So sick of teachers showing off how smart they are by talking over students. You actually teach. Thank you for your brain and your humility.

very well elaborated, you may have just saved my science's upcoming final exam this week. much thanks to you! :)

Great job, Tyler. I'm using this entire series to teach my high school students about the development of atomic structure.

If I would of had you as an instructor my life would be different- This is the understandable explanation I’ve always wanted

I wish my country had this kind of teacher but our country does not promote talent but they want 90 % in every subject U ar the best teacher may Allah bless u

you are literally saving my academic life I am not even kidding, the videos you make help me with so much stuff we do in physics (i am aware that this is chemistry but there seem to be some overlappings) thank you from the bottom of my heart

I'm a science teacher and your videos are of huge help to me and to my students for independent learning sessions. Thank you so much. God bless you and more power.

This is really really helpful, I was confused by my school's chem txtbook but then I watched your video and finally understood clearly thanks sm.

You are ridiculously Good. Would be great if you enlist your lectures Topic wise in separate playlists... like Physical Chemistry, Organic, Inorganic and Basic Chemistry all in separate playlists.

thank you for helping me survive chemistry we need more teachers like you

I do like you enthusiasm and teaching skills Tyler. Clear explanation of concepts. Thanks.

You are literally the only person I learn from on KZfaq. Clear explanations attacking every point with laser beam precision. It would be a dream come true if u had the time to make a video on a topic practically my whole class is having trouble with: Lattice Energy (: Thank u for all u have done for us! (: God bless u

Without your explanation, I don't think I would have understood my exam material. Thank you.

Thank you so much for this awesome video. I really love the cutout paper add-ins - it really helps me to picture it in my head!

every school should deserve a teacher like you..you are amazing!!

great joke about wrapping gold foil

This video was very helpful ! When my teacher explained it, I was confused but now I understand it - thank you so much !

I really like the way you teach. It’s so much more comprehensible than the fast and furious lectures that my teacher gives.

Well done, Tyler. You are an efficacious & inspiring teacher. I grew up watching Carl Sagans' "Cosmos." He both entertained and inspired, as you do. You remind me of him. Brilliant work!!!

Who is watching this from india 😅🤣

This guy puts so much effort into his videos. Thanks!!!

BRILLIANT . I wish we had a teacher like him to teach us science. It becomes so interesting when taught in a right way.

this is the absolute best explanation of the gold foil experiment i have ever listened to. thank you 100000000X

This is truly magnificent teaching. Thank you very much for your effort and contribution!

Thanks to you, I kinda get chemistry more and it just makes me to learn more about chemestry. Chemestry seems pretty interesting now

For me the predictions part was confusing but now it’s crystal clear… Thanks😊

I'm discovering my books are seriously lacking explanations of experiments. Your videos are proving most helpful. Thank you

I study in french but your videos are always a great help, thank you so much.

Man no actually sir I just got blown away by your details and explanations it's just amazing I was able to understand each and every thing tat u taught one of the most informative and helpful video I have ever seen

Explained in a great and simple way. Thank you very much, this has been a great help.

the world needs you for 2021

Im your new fan…. Just started a bachelors for biochemistry… i love your videos so much but i have only watched 2 so far

It's a good teaching methodology making the getting things more effective, correct and effortless. Thanks

Tyler I really enjoyed the way that you want to teach us some chemestry discoveries. I am french and actually I think that I have already understood all the points of your lesson. Thank you so much for your work, now it will be esier for me to learn the atomic model of Rutherford

I love every one of his videos! This man is so talented, I wish we had more professors like him!!

I love your work you really help me out a lot because my teachers never explain things like this, "or say zooom" , they just give out a pamphlet with drawing and explain very little, thank you for your work, and never stop no matter what , thanks

You're such an amazing teacher!! You deserve to be a lecturer in a university 💖

You are amazing bro . Keep it up And Congrats for your 450k+ subs....🎉

Excellent explanation! Wish to meet you someday

Tyler, I also am a teacher. I hope I will be able to teach like or better than you in the future. You are a professional role model and an inspiration too. Thanks for choosing the teaching way and thanks for always been there.

with your videos this all is actually so much fun

No words!! Even if i use each and every word of every language of this world to thank u and praise ur hardwork, it wouldnt be enough! The way you expalined is beyond any word!! May God help you in ur work!!! and wish God make me a person like you who uses all his strenght and intelligence in helping people!!! No words!! speechless!!

This video helped me to organize the main points about this experiment in my head, thank you very much!😁

Your explanations are great. Congrats

Excellent illustration and explanation!

Awesome video. Explained very well and clearly. Thanks!

u just helped me pass my chemistry midterm thanks! :D

Thanks for teaching so patiently and better than textbook syllabus

so so helpful. watching your vids make it so much easier for me !!! thank you ty

this video is VERY helpful! thank you! do you mind telling me what exactly the circular material is made out of?

Thank you. Your illustrations about the experiment simplifies for me amd made me better understand it. Keep going. ما شاء الله

hey, can you add few more link that I can use for my research?

Thank you so much for your help ,I really need teachers like you in my life .Thanks and that is from Egypt

Simply outstanding. You get a gold star for teaching this. It clears up a lot of questions I had about how the model of the atom as we know it today evolved over time. Simple, but accurate. God bless you, man!!!

totally saved me from school... i cant understand much when im in school but this video made me understand what my teacger said more! really wish there is a professor like you if i go to college... soo goos at explaining!

This video helped very much. Even my teacher didn't explain this much . THANK YOU

I feel so enlightened now. Thank you Tyler. Love from Myanmar.

This is such a helpful video, so informative and clearly explained. Thank you :)

You are honestly incredible. Amazing explanation.

tyler can you group some of the related videos?? its difficult to find them 1 by1

15 minutes & 50 seconds with this guy & I'm learning more than I've ever learned in all 7 months of my physics class #yay

I don't understand where the alpha particles came from. Didn't they just barely discover that atoms weren't the smallest particle (thanks to the discovery of the electron)

Thank you, was struggling to explain why it happens, but the video clears everything up for me.

U are the greatest teacher in the world. i wish in my school teachers like you comes to teach us

Thank you so much. I finally get the concept of his experiment. It's really hard to understand this concept by simply reading what's written in the book. Terminologies are too hard to understand making it hard for me to imagine it.

I have a question. How do we know that the nucleus is in the middle of the atom?

Tyler Dewitt, you're the best Chemistry KZfaqr ever! I Liked your videos before I even finish them just because I already know it's gonna be great. Thank YOU for the awesome videos.

your explanation is great! keep up the good work.

Hi Friend, My name is Amit. In your video at 12:20 I have a question. I would like to know what made him (rutherford) think that, that the positively charged dough is so light and not dense. I just wish to know. I understand that we can't go inside his mind. but you are explaining so well that I am curious. why he did not expect that it will bounce back instead of easily pass through Plum Pudding....? Please Reply. Thanks.

Thank you so much, for making me understand as my English is a secondary language. I got a lot of help from you. not only that I didn't have a base in chemistry also.

awesome way to explain this experiment!! With the help of your videos, Chemistry is going to be less stressful!!!

Can you please explain the.defects in th is thoery thatnwere c Eared by dalton atomic theory
