Phosphorous (P) and chlorine (Cl) bond covalently to form the important industrial compound phosphorous trichloride. The diagrams below show the electron structures of phosphorous and chlorine.Which diagram shows how the covalent bonds most likely form in a phosphorous trichloride molecule?

The compound cyanogen (CN)2 has covalent bonds shown in this diagram.

In carbon dioxide (CO2), there are two oxygen atoms for each carbon atom. Each oxygen atom forms a double bond with carbon, so the molecule contains two sets of double bonds.Two sets of double bonds means that the total number of electrons being shared in the molecule is
