The electronic configuration of nitrogen

N (7) = 2, 5

Phosphorous

P (15) = 2, 8, 5

N

is more electronegative than

P

From top to bottom down a group, electronegativity decreases. This is because number of shell increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.
