The compound carbon tetrachloride is formed when a carbon atom shares electrons with four chlorine atoms. What type of bond is this?

Electrons are shared, thus it is a covalent bond.

it should be p1 v1 = p2 v2

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
