Well, the electron configuration of Cu is [Ar] 3d^10 4s^1. So, Cu+ would be [Ar]3d^10 since you're taking away an electron. The principle quantum number would be n=3 since that's the coefficient of the d-orbital, and the angular quantum number would be l=2 since n-1 is equal to 2. Also, when l=2, an atom can have a d-orbital.
