What is electron configuration of Bi5+?
Here is the Bi neutral atom electron configuration. Take the last five electrons away to make the Bi^+5 ion.
I don't understand why it's like that -
Shouldn't it be 6s2.4f14.5d10.6p3
And then with the charge 6s2.4f14.5d8
No, it should be as stated. While it may be true that the 4f and 5d levels are filled before the 6s or the 6p, the fact is that 6s and 6p are the OUTSIDE shells and those are the VALENCE electrons. So you remove the outside electrons from the outside shells leaving you with [Xe] 4f14 5d10 for the Bi+5 ion.
