Answer :
Nitrogen atoms commonly exhibit a valence of 3 as they typically form three bonds with other atoms to achieve a stable octet structure, such as in ammonia (NH3).
In the context of chemistry, nitrogen typically exhibits a valence of 3.
This is because nitrogen, as an element in group 15 of the periodic table (or the 'Nitrogen Group'), has five electrons in its outer shell but it only needs three more electrons to complete its octet (eight electrons in the outer shell), which is a stable configuration.
Therefore, nitrogen typically forms three bonds with other atoms.
For example, in ammonia (NH3), nitrogen forms three bonds with hydrogen, each bond representing one shared pair of electrons.
Nitrogen is generally trivalent in compounds where it carries no formal charge, forming three bonds with other atoms.
