(b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).b) P4 is non polar covalent.

CH4, methane, is a gas, and the bonds are 97% covalent. SO4^2- is the sulfate polyatomic ion. The bonds in sulfate ion are 83% covalent. In Na3PO4 the bonds in the PO4^3- polyatomic ion are 68% covalent and the bonds between O and Na are 80% ionic. Therefore, Na3PO4 will have high ionic character.
