Nitrogen atom need ______ electrons to attain octet in the valence shell.

$\text{N}(\text{Z}=7)$

Nitrogen atomic number $(\text{Z}=7)\text{\hspace{0.17em}\hspace{0.17em}E.C}\to \frac{1{\text{s}}^2}{\text{K}}\frac{2{\text{s}}^{2}2{\text{p}}^3}{\text{L}}$

Nitrogen gain ‘3’ electrons to attain nearest noble gas electronic configuration.
