f block electron configuration

[@---ml4jd]

f block screws everything.

[@pranaysai7713]

Exactly!!

[@arinafolayan6683]

Yes!!!

THANK YOU MAN!
Your the only person I could find that didn't use noble gas configuration.

[@angelamadrigales8998]

Thank you! Really helped clear up how to handle the f block 👍🏽

[@AdobeTracer]

Thank you David Walsh, when I was doing the electron configuration for Gold (Au) I was confused on where the 4f14 come from then it just went to 5d10 and 6s1 at the end. Now I still don't know why they want 4f14 if we go deeper for transition metals. Will figure that out soon. Trying to be come a bio-chemist.

David Walsh, you are my hero.

[@Bot-tm7hs]

this was a great video, but sounds like you are dealing with allergies or a cold with that nose

[@goldgemechu946]

Tnx for the video ..but u dont have to use dots ...u can represent using noble gas as a core like [Rn] 7s2 5f3

[@remus6846]

can you explain it to me this is what I am looking for me

[@GDPlainA]

​@@remus6846u can say its the shorthand notation (the simplified one)
for example, the electronic configuration for Fe is
1s²2s²2p⁶3s²3p⁶4s²3d⁶
we can shorten this instead by using a noble gas with an atomic number lower than that for Fe, which is Ar
the electronic configuration for Ar is: 1s²2s²2p⁶3s²3p⁶
so we can use that and simplify into [Ar] and then continue so we dont have to keep on writing 1s²2s²2p⁶3s²3p⁶
so for Fe, the shorthand notation will be
[Ar] 4s²3d⁶
and this looks way shorter isnt it

Amazing absolutely brilliant

[@Mafefkownik.]

Thank you! I have test tomorrow and you helped me a lot (sorry if i wrote something wrong, i don t know much english).

[@gasmaskboi6904]

Thank you and have a good day.

[@michellewest6929]

Thank you sir! Really helpful!

[@jorjeyyyy222]

How do you know the valence electrons of f block groups?

[@katerinamasic5022]

The electron configuration of Pa in the video doesn't align with what google says or other RUclips videos?

[@kingcobra3329]

My professor or teacher is having me use a different periodic table, one where the S's have a third row including: Sc, Y, La, and Ac, at the bottom in the f region it's 58-71 and 90-103, which version is correct?

[@mariawirfel5418]

this periodic table and method is correct

[@kingcobra3329]

@@davidwalsh4545 Thanks.

[@fathimashaik1241]

This helps a lot, thank you! I just have one question, would the electron configuration for gold be written like this: [Xe] 6s1 4f14 5d10?

[@danifierro8321]

i know this is late, but yes it would be [Xe] 6s2 4f12 5d10

[@inversedq2190]

@anasipka5636 i know this is late but Its because the fully filled inner orbital is more stable than fully filled outer orbital and an empty inner one

[@ehsanmunir7404]

Great example on the Neodymium, but what I'm tripped up on is the actual Energy Level presented on the Periodic Table for Protactinium, it's actually 2,8,18,32,20,9,2 What confuses me is that 9 clarifies that there is an extra electron in the 6th Energy Level instead of the 5th Energy Level (Presumed to be taken away from the 5f, correct?). Why is this?

[@nirmalkumar1297]

Good work.thnx sir

[@MusaSalman-q6h]

Thanks, super helpful!

[@Wahib1610]

I love you❤

[@pinchetii6555]

Thank you

[@sabprogroup8623]

everywhere shows different things wtf, but i get it now here.

[@shahin2324]

Thanx for the video!!!

[@jesuslanderos.2442]

Why does, in many pages, say that the electron configuration of the Pa has a 5f2 instead of 5f3?

[@Microplstics]

thanks I have an exam tomorrow

[@Az-no9tq]

thank you so much sir

[@kofiowusu8410]

I got atesttomorrow
