How many lone electron pairs are present in ${\text{N}}_2$?

A nitrogen atom has $5$ valence electrons. In a dinitrogen (${\text{N}}_2$) molecule, the two nitrogen atoms share three pairs of electrons to form a stable triple covalent bond ($\text{N}\equiv \text{N}$).Out of the $5$ valence electrons on each nitrogen atom, $3$ are used in bonding.This leaves $5-3=2$ non-bonding valence electrons (which equals $1$ lone pair) on each nitrogen atom.Therefore, the entire ${\text{N}}_2$ molecule contains a total of $2$ lone pairs of electrons (one pair on each nitrogen atom).
