Covalent Compounds form when two nonmetals and/or a metalloid and a nonmetal bond
To name covalent compounds • Covalent compounds are composed of two or more nonmetals which share electrons. (Some metalloids are covalently bonded as well). • USE PREFIXES mono = 1 penta = 5 di = 2 hexa = 6 tri = 3 hepta = 7 tetra = 4 octa = 8
