Electron Configuration for Copper (Cu, Cu+, Cu2+)

Therefore, one of the 4s2 electrons jumps to the 3d9. This give us the (correct) configuration of: 1s2 2s2 2p6 3s2 3p6 3d10 4s1. For the Cu+ ion we remove one electron from 4s1 leaving us with: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10. For the Cu2+ ion we remove a total of two electrons (one from the 4s1 and one form the 3d10) leaving us with.
