Very good illustration! The illustrator is a gifted teacher!

[@wrox9684]

Love his accent

[@Ayana781]

Yes

[@sakshisharma4069]

Loved it finally I understood what is energy bands.

[@rithikkumarc]

I usually don't comment in yt .. but i gotta admit ........ Best Explanation Ever.... 🎉🎉

[@namraaah271]

The year is 2023 and I'm preparing for boards which btw I'll fail. It felt good to come back here and see why I had chosen science in the first place. I see exactly why I chose science and I'm grateful for teachers like u.Thank u and sorry for the drama lol

[@wetoocandoit]

did u fail

[@winter_daisy]

How are you now?

[@EyeGuy2766]

and my teacher explained this in idk what language for 2 hours until my entire class slept and he finally left the class

[@shubhkapoor4057]

this was by far (for me) the best explanation of band theory... THANKYOU SO MUCH!!!!!!

[@RohitSharma-rw7qu]

Great sir ..
No doubt remains...
Perfect explanation

[@rkcoder]

Khan Academy never fails to provide brilliant videos

[@danishislam3766]

First time I saw someone clear this concept ... brilliant sir

[@talhaakram4165]

Yup! I got it very well.Thanks a lot bro and keep it up!

You sir deserve the greatest head ever known in the existence of man, thank you for explaining this concept in such a simple way.

[@lurker16]

Wonderful lesson. Thank you, from an italian student :D

[@lurker16]

@Spiritual Nature yep, i study at the polytechnic of milan

[@lurker16]

@Spiritual Nature at the moment I study aerospace engineering. After that, if everything goes right, I want to continue with a specialization in space engineering. What about you?

[@lurker16]

@Spiritual Nature well thank you, hope you will be able to pursue your studies. I’m 20 btw.

[@lurker16]

@Spiritual Nature yeah mine too. It was open until the end of october.

[@adilafarsanavn3925]

Most beautiful explanation ever❤❤❤

[@devinadebnath6257]

Ahhh ,I love this explanation of bands

I must admit that I got a perfect teacher for my concepts.Thankyou so much

[@soniaverma7870]

Absolutely the easiest explanation ! Thankyou so much sir 👍

[@FD-rt3rv]

fantastic! thank you! free clear explanation vs my expensive uni professor difficult/foggy formal explanation. Universities need to adapt or die

[@vidyadhoble9120]

great .....great ......explanation.
it really helped me

[@likhith862]

best video on band theory!!....

[@aswinzed8339]

Thank you 😊
Great explanation and teaching 👏

[@rudrakshadixit912]

absolutely loved this video! cannot thank you enough, Khan Academy

[@themarvellous]

Now absolutely understand what my teacher is trying to say🙌😅😂😂😂👏gosh no one explain like this.

[@MuhammadYasin-nb1ke]

Wow i learned from a lot of videos but couldn't get it till I find this video 👏

[@adilafarsanavn3925]

Heartiest gratitude ❤❤❤

[@divyanshtiwari5540]

Thanks for this.. You doing a great job ❤️

[@lovemyself5969]

You gave such a clear concept thank you so much

Yeah!!! I got it😉😉.. best explanation 👏👏 Thanks so much..

[@osamazahid715]

You the great, keep it up bro

[@intheshell35ify]

Whoa. I knew there had to be something making free electron movement happen but I didn't know it would be that pretty.

[@chapawanniarachchi9084]

Very helpful,Thank you very much

[@EngineeringDiariesLK]

what a great explanation🔥

[@JesusTorres-yr9kw]

Thank you god for Indians

[@moizzazahid3766]

Woahhhh!!!! COULDN'T ASK THE CREATOR FOR A BETTER EXPLANATION 🙏

[@nish9421]

Wow its amazing

[@tales124]

Hey, how do you know that when isolated atoms will come together and will form molecule then different atoms will have exactly increasing s,p or d orbital energy level?🤔

[@zaheersuhabuth2677]

Best explanation so far on UA-cam ;)

[@sindhugummadilli3662]

I amazed to these lecture

[@youtubeessentials2996]

Awessssoooommmmee 😍😍😍😍

[@sneakygrass4617]

Thank you so much sir ,now it's totally clear what it is about

[@user-bn6jp8qo8e]

Perfect!
I learn to the video from my material class
I think it very well

[@yashyelmame1460]

Beautifully Explained. I read ncert in half and hour and you taught me the same thing with more depth and clarity in 8 minutes wow!

[@rathaprasi6135]

I read for more than 2 hrs..😂now I clearly understood...but .. how conduction band is formed as given in NCERT.for si atom ..I'm bit confused

[@ramygamal996]

May
i ask why you consider p orbital like s orbital with 2 energy levels? We know it is has more orbitals than s

[@JS-yg7fy]

I must really thank you making me understand this topic .Thank you so much.

[@hoffmanmustardoil6191]

So, Pauli's Exclusion Principle is the fundamental idea about Quantum Entanglement...

[@amira66996]

Thank you so much 😊
You are awesome 👌 👏

[@anasabidullah8670]

i got all my answers!...........you did a very good job

[@socialbeing6846]

Very useful video

[@nineteentwentytwo]

Now (after 7 months ) I finally understood it!

[@patakotisrinivas1918]

Nice explanation sir

[@mariamislam2632]

I got it.
Thank you so much.

[@sayedahemad39]

Crystal clear concept thank you so much

[@user-wd7nt7wg1e]

Thank you
Excellent explanation for band theory 👏

[@Gamer_10936]

Beautiful explanation
Thnx !

[@harini4143]

awsome video 🥰

[@yuvraajbhatter2669]

i love you bro, you made me understand shit for the first time

[@kisho2679]

How much energy has each level and every band in concrete?

[@kewaltakhellambam7710]

made it so much easier

[@utkarshprithviraj2238]

sir there isnt a video about molecular orbital theory in the khan academy arsenal....could u make one pls

[@poojakulal1154]

Why unpaired electron present in 3s orbital doesn't go to bonding molecular orbital?

[@preethipara8028]

I think, as the spin quantum number is same... that's why they are not paired

[@nehadas02]

thank you from USA !!

[@aryensujjan]

from which reference book you get this theory??

[@bhumikasoni6260]

Very very awesome and crystal clear explanation 😍😍

[@runzit2007]

Excellent 👌👌👌👌👌

[@itsnotrocketscience3083]

Thank you very much

[@ShivKumar-yz6fv]

That was so neat !

[@physicsdiva1871]

Well explained

[@sayit12345]

finally, after 22 years of my life i understand the band theory 😄

[@abhijithaldar2231]

Why is the width of the band increasing when we will go from lower level to Higher level?

[@amanshah6885]

WOW 😲 THAT WAS AMAZING

[@LostWings5]

I have a small doubt sir, in the molecular orbital energy level diagram of Na2 molecule I see that two electrons have occupied different energy levels in 3s orbital even though there is space for the electron to be occupied in a lower energy level. Pls someone clarify me😅

[@vivekthumu8992]

Super sir

[@aryensujjan]

Excellent 👌

[@crownchemistry9742]

very easy explanation sir

[@Ayana781]

Pauli is now happy ,🙌👌😄

[@siddharthrajan616]

Loved it..love physics ❤❤

[@user-zp2vg4ps8q]

This is not physics...

[@AhmedMujtaba-qq3mi]

​@@user-zp2vg4ps8qwhat is this?? Biology😂

[@aaditya3766]

lit.you are a gift,bruh

[@iraklisk6288]

Thank you! you are a great teacher :)

[@prabathjayasundara]

Superb🤩🤩🤩

[@sachinrath219]

why the energy levels are shown by a hirizontal line,what scale is used to signify it,is it any scale on a graph,thanks.

[@mulukutlavenkatahanumantha8913]

Very clear thank you very much sir

[@varshinisingam631]

Thank you sooo much sir 🙏🙏

[@ashwinsoni4568]

Finally i understood what energy band is
....
A big thankyou sir..😊😊
