The first nonmetal is S sulfur. The second nonmetal is O, named oxide. The subscript 3 of O is shown as the prefix tri. SO3 → sulfur trioxide The subscript 1(for S) or mono is understood. Naming Covalent Compounds (Continued) General, Organic, and Biological Chemistry Copyright © 2010 Pearson Education, Inc. 6 Name P4S3 The first nonmetal P is phosphorus. The second nonmetal S is sulfide. The subscript 4 of P is shown as tetra. The subscript 3 of O is shown as tri.
