For both A and B, determine if the bond described is nonpolar, polar covalent, or ionic. Indicate the direction of the polar bond and include partial charges, if needed. A phosphorus atom (electronegativity value = 2.19) single-bonded to a fluorine atom (electronegativity value = 3.98). A carbon atom (electronegativity value = 2.55) single-bonded to a sulfur atom (electronegativity value = 2.58).
