Final answer:
In an N₂ molecule, there is one lone electron pair on each nitrogen atom, resulting in two lone electron pairs total.
Step-by-step explanation:
The number of lone electron pairs in the N₂ molecule is one on each nitrogen atom.
Nitrogen has a total of five valence electrons. In N₂, each nitrogen atom forms a triple bond with the other, using three of its valence electrons for bonding. The two remaining electrons on each nitrogen atom form a lone pair.
Therefore, in an N₂ molecule, there are two lone electron pairs in total, one for each nitrogen atom in the molecule.
