SUMMARY
The electron configuration of the cadmium ion (Cd2+) is [Kr] 4d^10 5s^0. In its neutral state, cadmium has the configuration [Kr] 4d^10 5s^2. When forming the Cd2+ ion, electrons are removed from the 5s orbital first due to its higher energy level compared to the 4d orbital, resulting in the configuration [Kr] 4d^10 5s^0.
