The following question relates to a first year chemistry course that I teach.

Cr ground state is [Ar]3d^5 4s^1

What would be the ground state for Cr^-1 ?
Explain the e- configuration and estimate the relative energy difference 
between Cr and Cr^-1.

Discussion and comments welcome.

Best,
Laurence Lavelle
