Naming Binary Molecular Compounds

Binary Molecular Compounds § Compounds between two nonmetals § First element in the formula is named first. § Keeps its element name § Gets a prefix if there is a subscript on it § Second element is named second § Use the root of the element name plus the -ide suffix § Always use a prefix on the second element

§ 1 = mon(o) § 2 = di § 3 = tri § 4 = tetra § 5 = penta § 6 = hexa § 7 = hepta § 8 = octa § 9 = nona § 10 = deka List of Prefixes
