Question

The ground state of Nitrogen (Z=7) can be written in terms of ?nlm and the spin states of the electrons. Which of these would be one of the degenerate ground states of Nitrogen? (We do not need to write out the fully antisymmetrized state. It is assumed and possible as long as no two electrons are in the same state.)

a. ?100? ?100? ?200? ?200? ?21P1? ?210? ?211?

b. ?100? ?100? ?200? ?200? ?21P1? ?21P1? ?210?

c. ?100? ?100? ?200? ?200? ?21P1? ?210? ?211?

d. ?100? ?100? ?200? ?21P1? ?21P1? ?210? ?211?

e. None of the above
