Electron Configuration Sub shells and orbitals

[@jazlynbell8202]

I kept getting that "omg I get it" moments. THANK YOU .

[@jazlynbell8202]

OMG I GET IT

[@zubayershams6174]

I am doing my A levels chemistry on my own just seeing your videos. Very helpful

[@aileenwu1362]

Thank you so much!!!! Even though I'm not taking A Levels (I'm in the US), your videos are really helpful.

[@AlleryChemistry]

+Aileen Wu I'm pleased they are helping people like you across the pond! It just shows how universal chemistry is ay! 👌

[@averageaviationgeek9318]

This video REALLY helped me out alot, Thanks and keep it up! Students need teachers like you!

[@maxc4534]

this video is very useful for my AS thanks

[@AlleryChemistry]

Brilliant! Hope you're enjoying AS chemistry so far.

[@johnvincent1543]

Thanks man really helpful for our online class, keep up the great work

[@atiarimi7322]

Thank you for this video, it was really concise and straight to the point!

[@baekhyun432]

thank you so much ...I found this really helpful ....This makes the As chemistry much easier

[@shakilmpatel]

So easy to understand..Top teacher

[@emmanuelbaptiste5353]

very clever..I like it keeps up the good work

[@AlleryChemistry]

+Emmanuel Baptiste Thanks very much! This video replaced an old one that was not very clear in terms of video quality.

[@ornulusoundeffects6423]

Didnt know i will have to revise this topic after getting into Medicine (by getting A grade in Alevel chem thanks to allery chem :D)

[@Goodfellas981]

Do we need to know about Sigma and Pi?

[@theshadeofjett]

I get confused we used these sub shell ideas but in chemistry later on they go back to the GCSE shells..

[@AlleryChemistry]

Yup. Shells exist it's just at A Level you also need to know that shells are made up of sub-shells (s,p,d,f) and these are made up of orbitals.

[@lanasadeddin9219]

I don't get the part where you said that Copper has a full d subshell and that means it has lower energy and hence more stable.Why does it have lower energy and why does lower energy make it more stable?

[@holly5140]

Hi! Is it just Cr and Cu that follow the 4s1 electron rule or all transition metals? Thanks

[@lynapl4ys]

4 years later and bro doesn't know :(

[@milko5143]

7 months later and bro....... still doesn't know 😢

[@ashutoshaarav3017]

u had written carbon-1s,2s,2p but the value of p=6..then how we can write 2 there????

[@AlleryChemistry]

There are 6 electrons in total in a carbon atom. 2 in the 1s orbital, 2 in the 2s and the other 2 go in the 2p sub shell. Hope this helps.

[@ashutoshaarav3017]

thanks....

[@elliestephenson202]

Ashutosh Mahanta it doesn’t always have to be the maximum amount of electrons that orbital can hold!

[@rodaynaraydan1076]

why does vanadium have an electron configuration of 1s2,2s2,2p6,3s2,3p6,3d3,4s2 but the order is always 3s,3p,4s and then 3d. different videos have different answers,can you please explain

[@Study-learn]

Hi sir, in 3:37 you mentioned 2p (B,C,N…) 3p (Al,Si…) but what elements are 1p if He is 1s?

[@akkoei8822]

There is no 1p as the p orbital is not in the first energy level.

[@annamarie.u]

When writing the electronic configuration for Se(the shortened version), can you only use the closest noble gases in the bracket? Why not (Cl) 3p6 4s2 3d10 4p4 ?

[@harszet1063]

Very well organised and thought out. Love ur vids

[@robertbrodie9566]

Why does it go 3d and not 4d?

[@hajrar7448]

Thanks, this is helping a lot!

[@AlleryChemistry]

+Hajrar Ikhlaq Good good! Please share the vid! 😄

[@slickgt1146]

Goshhh this video is brillianttttt thank you❤️

[@deen2jannah375]

Hi is this part of the new spec, Thank you

[@buttersquids]

Very helpful video

[@AlleryChemistry]

Glad it was helpful!

[@ChattyCinnamon]

Thanks a lot man

[@shakilmpatel]

LOl that twitter on right corner
really helpful

[@jimmybobjim6658]

I love you.

[@tusharsirschemistry]

Excellent sir,u r A1

[@papatee0413]

Thank you!

[@AlleryChemistry]

You're welcome!

[@herngchang6677]

Thank you so much for this

[@hibasyeda5174]

Thank you!!!!!

[@AdhisWorld]

Thank you

[@AlleryChemistry]

You're welcome 😊

[@flightlesslord2688]

did you ever hear the tragedy of Darth Plagueis the Wise? Also this is useful, cheers

[@jensenkahwa3470]

sorry is exdexcel part of cie

[@AlleryChemistry]

No. Different thing.

[@22alison19]

He is found in the S block ! isn't it?

[@rpsi]

THANK YOU THANK YOU

[@AlleryChemistry]

Welcome!

[@nutscoconuts8449]

[@omarhuge]

Carbon is written incorrectly. It has 1 electron in the 2s orbital and 3 electrons in the 2p orbital because it forms 4 bonds, they are both half filled so they become more stable.

[@oladipo0]

Only in its excited state

you are my dad
