electronic configuration for Co+4? how many unpaired electrons?
The ground state electron configuration of Co is:- 1s2 2s2 2p6 3s2 3p6 4s2 3d7
In order for the metal to become a +4 ion, it must lose 4 electrons. The first 2 will be removed from the 4s sublevel, since it is part of cobalt's highest numbered energy level. The next two will come from 3d, which will leave that sublevel with an exceptionally stable half filled configuration.
electron configuration of Co+4 is:- 1s2 2s2 2p6 3s2 3p6 4s0 3d5
So there are 5 unpaired electrons.
