Okay, so as far as I remember, only Cr, Mo, Au, Ag, Cu only follow the weird distribution of electrons (half filled s or half filled d) in the ground state. When things are ionized, however, do every element follow the irregular pattern?
Because, Zn, when it becomes Zn2+, it seems to lose electrons from 4s shell instead of 3d shell to maintain fully filled 3d orbital.. Nickel, which has same electron configuration with the Zn2+, has 4s2 3d8.
So what is it? Is there a rule I can follow to determine this?
Thanks in advance.
