Cadmium has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10, commonly written in the shorthand as [Kr] 5s2 4d10. For students who have not learnt spdf notation, the configuration is normally written as 2, 8, 18, 18, 2. It has two valence electrons.
The ion would have 8 instead of 10 as the last number.
Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 Short-hand version: [Kr] 5s^2 4d^10 Note: The "^" symbol means the the following number is in the form of a superscript.
