Ionic compounds are between metals and non-metals. Molecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals) An io â¦ nic compound is a pure substance that is formed from a metal and a nonmetal.here are two important types of covalent bonds: non-polar and polar bonds.
