Khan Academy has never failed to dumb anything down to my level

[@saffrown]

you know the video is good when the comment section is flooded with thank you's

[@ninjanerdstudent6937]

I swear by god, it took 3 hours for the professor to explain this in class and I never understood it. 12 minutes on here, and I got it. Understood. College is truly just for the credential.

[@meloniejen8400]

It's confusing but isnt this a grade 12 concept?

[@KT-ki8ik]

@@meloniejen8400 first year chem in uni covers this - I know cause I'm watching it rn to review for my exam tomorrow worth 53% of my grade :)

[@meloniejen8400]

@@KT-ki8ik *53% ?!!*

[@KT-ki8ik]

@@meloniejen8400 yep, all multiple choice too because profs can't mark hundreds of papers at the end of the semester so they do scantrons instead - so no part marks

[@meloniejen8400]

@@KT-ki8ikOOF, do you mind me asking what major is this?

[@palacsintakat]

the angular quantum number can also be called Azimuthal quantum number. For anyone studying for mcats and things like that, I'm pretty sure that is the word used

[@starrysky1588]

palacsintakat I've read it's also called subsidiary quantum number

[@0hold]

Or secondary quantum number

[@starrysky1588]

WildCat AQW ohh thx didn’t know that before...just wondering if principal is primary.?

[@0hold]

Zahra Khan Nope

[@saileshpatra9463]

Yup it is n remembering that is difficult

[@lizn8412]

My prof explained this for 1 hour. I should have skipped class and watched this instead

[@ianjohns109]

i feel the same way. I often find youtube videos to be a whole lot more concise and informative

[@h32bro]

Lol yeah

[@cokezero8510]

they teach u this stuff in college this 9th grade chem in my school :/ ...

[@genevievevan8588]

i still dont get it

[@stoddardtutoring6733]

I explained this in shorter time and even spun a top upside down, for students that don't have such a toy. kzbin.info/www/bejne/g5K4f3dua9Sia7M

[@MonkeyDLuffy-xr4fl]

You deserve an award

[@macbeth9301]

Yeah! Sure

[@justzach3204]

I am so happy this video exists, because my chemistry teacher doesn't even teach!!! I mean why even have teachers if they don't teach!?

[@nikodix]

Maybe they're cooking meth on the side...

[@jewelp4189]

UltraRockHamCake same here

[@verymadcitizen9798]

Same my professor doesn't do her job in my uni

[@bambibloggerfantage]

Amen! My chem teacher did nothing to explain this. I happen to be wracking my brain teaching myself 🙄

[@saminyasar22]

only to get money -- they don't teach for making u educated , they just teach only to get money

[@PinkPearlsForever]

THANK YOU!!! YOU ARE SO MUCH BETTER THAN MY TEACHER BLESS YOUR SOUL

[@leo-vr4yr]

UHG YES my teacher sucks- this guy explained in 12 minutes what my teacher would've taken an hour to! And I actually understand it

[@PinkPearlsForever]

+Shirley Z IKR!!! The struggle is soooo real

[@ShreyButle]

I'm getting the feeling that teachers either don't understand the material they are teaching or purposefully holding back because they know there are videos out there that will do their job for them.

[@sheldoncooper4204]

Shrey Butle well that or they just don’t know what their students know and don’t. Like they just assume that we understand it, because they’ve heard it like a thousand times. That differentiates teachers, it’s either they understand their students or don’t.

[@AaronTheRocker05]

I FUCKING GET IT!!

i think u r a fool. if you have learned something from this video then thank them or say nothing. U shouldn't use bad words

[@vaishnavkumars9261]

***** its ok bro i just felt like typing something ,you know right . Lol!! just for fun i am sorry

[@ani6167]

curious now since its been 9 years later , how has your life turned out since learning this

[@rajsrivastav_]

This concept was explained in the most brilliant way possible. Thank you so much Khan academy!

[@navkaur171]

this makes a lot more sense to me than my book. thank you! i am literally mind blowned!!!

[@educationalservices2518]

Navneet Kaur good

[@riteshreddy1871]

khan academy is the best each and every concept makes esier to understand

[@ntsuabxiong5755]

Khanacademy, you've saved my life! Thank you for explaining it so well! My teacher could not explain this at all!! Thank you!!!

[@Mac-xc7pt]

I watched this when I was a sophomore in general chemistry. As a junior in AP chem I finally found it, thank God. Same teacher from last year and barely just glazed over it.

[@Homie_fromjupiter]

This is way easy to comprehend!! My prof used to yap this for hours without actually learning something

[@OfficialMarkZuckerberg]

My professor is of a foreign origin and is very difficult to understand. you always help me understand the things that aren't making sense, especially since i am deployed and dont have tutors access. You're the real MVP!

[@anupamaaiyar8184]

The face who made me fall in love with chemistry and physics 😍💕💕

[@akunna1]

I never understood how all the quantum numbers and the diagrams were related until now! Omg you're such a life saver. :'D

[@averytwo1]

i got it during class then forgot over then weekend thanks for the review

[@alara102]

I GET EVERYTHİNG! I AM SO HAPPY THİS VİDEO EXİSTS

I gained more in a twelve minutes video than in an hour class. Thank you!

[@yasmeenahmed7989]

You've helped me a lot! God bless you.

[@Gargoyle-bc2ee]

may god bless your soul, I have a presentation about this tomorrow and I understood it from your video. you are a life savor

[@jaydangoldstein2683]

My gosh we learned so much of this over the last 22 years, love it totally understand all of it!!!!! ;-)

[@divyabhanot9876]

@jaydangoldstein do you have any relation with E Goldstein??😊☺️

[@ike_em_all]

I have my midterm in an hour THANK YOU SO MUCH!!!

[@dhimanghosh3423]

I think that all chem. teachers should be like u this was very good for me

[@505-p4l]

wow this was an incredibly clear and easy to follow explanation! Thank you

[@shaleemn]

Very easy to understand! Cheers 👍

Awesome explanation!

It is great helpful video

Good video but I still hqve no clue why the spin is +0.5 and -0.5 and not just +1 and -1 or any other arbitrary opposite values.

Thx a bunch man

YOU SAVED ME !

The video is very interesting! Something I don't understand: I have USDT in my OKX wallet and I have the recovery phrase. [pride]-[pole]-[obtain]-[together]-[second]-[when]-[future]-[mask]-[review]-[nature]-[potato]-[bulb]: How should I convert them into Bitcoin?

[@cody2013west]

thankyou thankyou so much

[@basiliacwalinski]

Great analysis, thank you! Just a quick off-topic question: I have a SafePal wallet with USDT, and I have the seed phrase. (air carpet target dish off jeans toilet sweet piano spoil fruit essay). How should I go about transferring them to Binance?

[@husnainajmal3346]

I actually was expecting you to go for n= 5 having 0 1 2 3 4 subshells...and draw something for f subshell and greater subshell.....anyways....a nice explanation indeed

[@niclacoste]

How do you determine which values for the magnetic and spin quantum number to use if you have more than one option?

[@aryanttt4023]

Wah!jio mere laal.

[@donnionnyola1685]

thank u for this

[@darthhp3386]

awesome things you have.. can you send the link of the video of khan academy's..that has abt derivation limits and integration of IITJEE level

[@xHaloxReviewerx117x]

What if the quantum number is 5? Or 7? The angular momentum number would be 4 for quantum number 5 (n-1) and 7 would 6 (n-1) so my question is what would the angular moment numbers be? For quantum number 5 would it be ;0,1,2,3 ?!

[@vidhumoulib9653]

thnx its nice

[@hyunxzseu]

Teachers need to explain more

[@TomAustinIII]

Cool!

[@elitecassidy8258]

Why can't professors explain stuff this easy?

You sir are a messiah to all of us. God bless you & may you live a long life! ☺

I have a question If l =1, one of the possibilities is 0. Can the orientation be a sphere or is it limited to the three p orbitals?

[@omvithalkar71]

Can u plzz demonstrate magnetic quantum number for the "d" shell

[@emilstrkr3776]

What do the 3 first quantum numbers mean for fermions other than electrons?

[@riggidyrickt7574]

thank you

[@jennylynpan9311]

Can anyone answer this How many electrons are there for an element whose last electron has the following quantum number n=5, l=4, m=-2, s=-1/2?

Oh yea, I got it!
