Mercury has the atomic number of 80 with the orbital configuration of [Xe] 4f14 5d10 6s2. With a net charge of 2+, there are two fewer electrons, leaving the configuration of [Xe] 4f14 5d10.
The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
