How do I do 5a because I know that Copper can have exceptions. Give the ground-state electron configuration expected for
each of the following ions: Cu^+

Re: CH 3 problem 5 [ENDORSED]
It would normally be expected for copper to have an electron configuration of [Ar]3d^9 4s^2, but since it would be a lot more stable to have a full d-orbital, it is rather written as [Ar]3d^10 4s^1. Thus, when an electron is taken away from the outermost orbital (s), it becomes a positively charged ion with configuration [Ar]3d^10.
