Consider the model of the nitrogen atom. Three concentric circles are shown. Inside the inmost circle are the labels P-7 and N-7. The center circle has red dots at the north and south positions. The outer circle has five red dots evenly spaced around the circle; none of them align with dots in the center ring.

Which electron configuration matches this model?
