The Lewis electron-dot structure for phosphorus trifluoride (PF3) would show phosphorus in the center bonded to three fluorine atoms. Phosphorus has 5 valence electrons and each fluorine has 7 valence electrons. Three of phosphorus's valence electrons are used to form bonds with the three fluorine atoms, and the remaining two electrons remain as a lone pair on the phosphorus atom. Each fluorine atom also has three lone pairs of electrons. Therefore, the correct answer is:

b. 1 nonbonding pair and 3 bonding pairs.
