Valence Electrons for Cu2+

[winnie bear]

Copper is one exception where e- config is [Ar]3d^9 where 1 e- is taken from s subshell and added to d subshell.

Since the # of ve- is based on what's in the s and p subshells after the [core], and d subshell included only if it's not completely filled (<d^10), would the ve- for Cu2+ be 9ve-?

I wasn't sure if there was an upper limit on the # of ve- a species could have (i.e. octet).

Yes it would be 9. There is a limit on the valence electrons for those with filled d orbitals or no d orbitals at all- where would those extra e-s go?

Honestly this is WAY to hard for the dat lol youre wasting your time.

Did you mean there IS a limit or no limit on # of ve-?

This was a part of an example that wasn't fully explained on Chad's DAT video. I first started with BIOL and was overwhelmed by the amount of info so decided to switch to reviewing GenChem first.

I only have my notes, Blue book, Crack DAT science, and Chad's videos to study for the Chem section. Have you taken the DAT? Any recommendations for GenChem? Thanks!

ehh there's not like set rules for this stuff. the answer for Cu2+ is 9. Count unfilled d orbitals. Forget about you're upper limit thing as it really isn't something set in stone.
Cu has 1 ve as its d orbital is filled. Get it?

I have take the DAT - Check my breakdown thread and hopefully some of my tips there will help you.

Just checked out your thread. Your scores are insane and I'm terrified! So did you apply this year or are you applying next?

i applied late this cycle. they r decent scores dont let them throw you. gl on your test.

30/30 for 2 of your sci are perfect, not descent🙂. The other scores are pretty bad ***** too. You're probably in so I should say, congrats now!🙄
