Achieve HW Week 2 #23

Hi everyone,

I was wondering why the excited state for an electron causes the electron configuration to be displayed out of traditional order in this question.

In the cases of chromium and copper, a completely full or half full d sub level is more stable than a partially filled s sublevel so an electron from the 4s orbital is excited and rises to a 3d orbital.
