Electron configuration of Cu+
« on: April 03, 2011, 09:49:57 PM »
Hey everyone,
Im not quite understanding the concept of electron configuration.

Cu+ is a transition metal which means it loses its highest n value since it is +

1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d ^ 9 or

[Ar] 4s^2 3d^9

since its losing its highest n value it will be [Ar] 4s^1 3d^9

However, the answer is [Ar] 3d^10

can someone explain why?
