Which of the following elements has 5 electrons in the valence (outer) shell?
A) C
B) B
C) S
D) F

Look at a Periodic Table, Nitrogen has 5 valence electrons (Oh, wait, that's not one of the choices)

And my answer is that nitrogen (N) has 5 valence electrons... the elment that you wrote doesn't have 5 valence electrons...
