I don't agree with your answer.
N is atomic number 7
P is atomic number 15
Electron configuration N = 1s2 2s2 2p3 = 7 electrons in 2 shells. 3 valence electrons.
Electron configuration P = 1s2 2s2 2p3 3s2 3p3 = 15 electrons in 3 shells. 3 valence electrons.
Which statement about nitrogen (N) and phosphorus (P) is correct?
They have the same number of valence electrons.
They have the same number of electron shells. ***
They are both inert.
They are both classified as halogens.
