Electron Configuration Sub shells and orbitals

A look at the electron configuration needed for A Level Chemistry. An introduction to the orbitals and how to work out the electron configuration from using the periodic table. A crucial part of Chemistry. Enjoy!

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

[zubayershams]

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

[aileenwu]

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

[averageaviationgeek]

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

[maxc]

this video is very useful for my AS thanks

[atiarimi]

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

[johnvincent]

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

[baekhyun]

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

[harszet]

Very well organised and thought out. Love ur vids

[emmanuelbaptiste]

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

Hi is this part of the new spec, Thank you

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

[rodaynaraydan]

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

[theshadeofjett]

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

[tamin]

Do we need to know about Sigma and Pi?

[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 ?

[ashutoshaarav]

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

[ornulusoundeffects]

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)

[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?

LOl that twitter on right corner

really helpful
