Based on the location of nitrogen cap n on the periodic table, how many additional electrons does a nitrogen atom need in its valence shell to satisfy the octet rule when it forms bonds?

Nitrogen is in group 15 of the periodic table, so a neutral nitrogen atom has 5 valence electrons. An octet is 8 electrons in the valence shell, and 8 − 5 = 3. Therefore, nitrogen needs three additional electrons to satisfy the octet rule when it forms bonds.
