... Note that the 4s-electrons were removed before the removal of the 3d-electrons. The reason for this is that in a metal cation the energy of 3d-orbitals is lower than the energy of 4s-orbitals (c.f. when filling electrons, the energy of the 4s orbital is lower than 3d-orbitals). Thus the valence elec ...
