NiCl2 is an ionic compound. It is composed of nickel (Ni), a metal, and chlorine (Cl), a non-metal. Ionic compounds form when a metal transfers its electrons to a non-metal, resulting in the formation of charged ions that are attracted to each other.

Fluorine is molecular, but it is an element, not a compound.
NiCl3 is an ionic compound. Nickel (Ni) is a transition metal with a variable oxidation state, which in this case is +2, and chlorine (Cl) is a halogen with a -1 oxidation state. The combination of these elements results in an ionic bond between Ni and Cl atoms.
