Identify the molecular formula of nitrogen trifluoride, which is NF\_3, indicating one nitrogen atom bonded to three fluorine atoms.
Recall that a single covalent bond consists of one shared pair of electrons between two atoms.
Determine the number of bonds by counting how many fluorine atoms are bonded to the nitrogen atom; each fluorine forms one single bond with nitrogen.
Since there are three fluorine atoms, and each forms one bond with nitrogen, the total number of bonds (shared pairs of electrons) between nitrogen and fluorine atoms is three.
Therefore, the molecule NF\_3 has 3 bonds or shared pairs of electrons between nitrogen and fluorine atoms.
