this one video taught me more in 14 minutes than 2 hours of college chemistry

A great combination of being very simple and easy to understand (step by step, terms all explained very well), yet energized and quick which helps keep the video more interesting.

Amazing lecture. I listened to my teacher for 50 minutes and was severely confused, but you helped me understood the concept under 15 minutes.

You're a life saver. I don't think anyone could have explained it any better! :)

I missed an entire lesson about ionization energy, electron negativity and affinity and I have a test tomorrow. Thank you! You saved me!

thank you for explaining it very well, I have a exam on our chemistry tomorrow and I'm confused about this topic great help dude :)

mate this video is splendid. you summarized the whole 2hr lesson in almost 14 minutes. thats awesome you have really helped .. i hope you do more videos like this

I appreciate that you treated electronegativity and electron affinity separately. Sometimes people confuse those two terms. Great work.

You're probably the most helpful guy on this topic. you've just earned yourself a subscriber.

Still relevant in 2019, helpful for understanding and great explanation

You explain this so well i always come back to this video when i need to review this stuff! Thanks a lot! Wish you were a prof at my school!

I have a final tomorrow and now I understand this completely! Thank you sooooo much!!!

Ya'll have this in college but we are having it in grade 8 chemistry these days and it's such a pain the butt and our teacher is so hard to get on the same page with... I wish I had this guy as my teacher! Awesome lecture thanks much

Thanks a lot for a good explanation. I have an exam tomorrow and did not understand a single sentence from my textbook but I understood it after watching this awesome video. Thanks a lot!

Thank You So Much! You explained it so well in just 13 minutes while it took my chemistry teacher an entire week and I still don't understand a single thing he talked about... Thank You soooo muchh! Greatly appreciated!

You are a beast at this. You literally explained this to me in less then 15 min while I struggles most of the class time on this.

you're a gift from heaven. thank you

You are a Pro! You have a great clearity in your voice, you are a great teacher!

you are probably the greatest chemistry teacher out there thanks man keep making more videos

You're a legend man. Best lecture on youtube about periodic table trends.

life would be so much easier if you were my lecture... thank you much! you explainations are so clear it scares me! u da King!

if u r the teacher then their is no requirement of books... and even no need to revise czz once u spoke something it has an unbelievable power to get in our mind permanently u rockk

Thank u is not enough. I read my lectures, somehow, I did not understand nor was able to picture these trends. I really like the fact the you just get to the point without any fuzz! Keep them videos coming.

1st online lecture i have ever understood... thank you so much.. please do another lectures in chemistry

i really got it now. it will help me alot for my exam on Thursday. thank you very much.

you the best none of these lecture explain like you do thanks exam in 2day now am prepared

I really loved how simple and great this was. Hoping to see more uploads like these

Oh my word. This is so helpful! I wish all professors made their lectures as easy to understand as you make yours.

You are a great professor. Your explanation is so simple and clear! Thank you.

This is SO helpful. Finally understand electronegativity! Thank you!

Thank you very much. Great to hear that my videos are helping others understand the simplicity in nature :)

I like the energy and passion u have towards this..

U r really awrsome... best teacher of chemistery on youtube!!

Very effective in mastering the trends of periodicity. Just wonderful.

Your the man! Made it all so easy to understand

Whah! This takes teaching and explaining to a higher level. Thank You very much.

Excellent explaination in a clear and simple language you are a good teacher

Yesss!! What a great video!! You are an amazing teacher! Thank You Thank Yoooou!

One of the best chemistry video ,,,keeep up the good work.

Thank you for the kind words. If you go onto my main channel page, you should find my orgnanic chemistry playlist. I believe I have over a hundred videso on different topics in organic chemistry. I will be adding many more in the near future, so stay tuned!

U r really better than my teacher in school in Ethiopia

Considering that an atom is not a solid sphere, the atomic radius is an approximation. We talk of electrons orbiting the nucleus in terms of probability and so an electron can be found as far away as you'd like (given that the probability decreases as you go farther). Therefore, no, you cannot take a ruler and measure the radius. But you can approximate it.

you explains things very well! I watched a few videos before coming here and this was definitely the best one.

This is just the best explanation ever.Thanks so much.

The best. That's all that needs to be said. Thanks man. Well presented and engaging. WOW!

This was highly informative. Love your energy.

Gr8 job andrey! 13 min of this vid was better than 2hrs of my reading :) I cant forget this even if i want to :)

Thanks for this video. It just simplified what I was really confused about.

thanks that really helped me a lot!! exam tomorrow!

I love the energy you have, it helped me stay focus. The Notes notes on your wall goes well with your lecture.

THANK YOU! This was so helpful I was totally lost before watching this

This helped me understand the trends sooo much better! My chemistry teacher explained it pretty well, but this gave me a better look at it and I thank you so much for the thorough explanations!! :D Cheers!

Thank you so much for making the lesson seems more easier. God bless you.

thank you very much! great to get comments like these! cheers!

thank u so very much ... this helped me to complete 7 pages of my fatty book in just 13 minutes

I'm studying for my semester final and this makes so much sense!!! Super helpful!!! Thanks so much for making it so easy to understand~

You're an excellent teacher! Thank you

Thank you sir. Nice video. easy to understand. Looking forward to watching more videos of this channel

very clear and concise details! Thanks for the help!!

Holy shit man 10/10 video. Makes crystal clear sense.

PRESSED AS SOON AS I SAW THE KEY WORDS I NEED TO STUDY

This man is saving me 7 pages of dry reading

Nice lecture. Just wanna add a point to electronegativity. When we talk about electronegativity we are considering a bonded atom not a freely existing atom.

Amazing... I didnt know we could understand so clearly with the coulomb's law

DAMN IF MA CHEMISTRY LECTURER WAS LIKE AK LECTURER'S I WOULD ACE ALL MA TEST

OMGGG THANK YOU1!!! I will donate, Im a struggling student but you explain so well!!! I have to donate just a little!! Thank for everything you do!!

very clear, make complicated things easy to understand, good job !

You're so much better than my Chemistry teacher lol. Thank you!

Omgg I didnt understand a crap my teacher taught in class lol but now I understand all this. Thanks so much for the lecture bro :)

Best lecture... Love from india..

i swear you are the best ! so much love

thank you a million. you explained much more better than our books. i have a single question, In the ground state of 33As; how many electrons have L=1 quantum numbers. thanks very much.

OMG, now i understand ..thanks man .. u r a genius ^^

Thanks! Happy to hear that.

you're welcome!

You are special you have brilliant mind❤

Hey! On my channel page, click the playlist "Organic Chemistry" and find the lecture on "Ionic Bonds". There, I talk more about electron affinity and ionization energy. Let me know if you cannot find it, I will message you the link.

Great to hear that! Will definitely continue making these videos! :)

This helped so much. Thank you.

This is so helpful, thanks for sharing the video...

Thanks for the help man.
