You do not go from 3p6 to 4s2, You continue with 3d10 until you FINISH the THIRD row (hence the 3s) then and ONLY then do you continue to 4s2 and so on. 🤦🏽♂️ some people
No. Whoever told you that is incorrect. The 4s orbital is filled before the 3d orbitals, so your method would lead to incorrect electron configurations, such as the one you just listed for arsenic, which is all kinds of wrong.
Excellent practice. Sometimes you think you've got it, but when you try to solve a problem, you realize that there were gaps in your knowledge.
About to take a test and this is the most I have learned in a long time! Thank you
love u sir for bridging stuff according to needs
Good teaching prof. Dave
thanks a lot Dave. this is really helpful!
thanks for the review!
Nice video
Great sir
How are you assigning the value for spin q.no?
always +1/2 or -1/2
Fanstastic!

hmm yeah what's going on! it's not tallying my views properly. grrrr.
I think the youtube views are broke again lol
Lol that was interesting

So the proper way for Arsenic would be 1s2, 2s2, 2p6, 3s2, 3p6, 3d10 then 4s2, 4p6, 4d7.
That is the PROPER way to do electron config
