  1. Binary Compounds Containing Two Nonmetals To name these compounds, give the name of the less electronegative element first with the Greek prefix indicating the number of atoms of that element present, followed by the name of the more electronegative non- metal with the Greek prefix indicating the number of atoms of that element present and with its ending replaced by the suffix –ide. Prefixes you should know: Mono Di Tri Tetra Penta Hexa Hepta Octa Nona Deca 1 2 3 4 5 6 7 8 9 10

  2. Binary CompoundsContaining Two Nonmetals (Type III Compounds) As2S3 • ________________ diarsenic trisulfide • ________________ sulfur dioxide • P2O5 ____________________ • ________________ carbon dioxide • N2O5 ____________________ • H2O ____________________ SO2 diphosphorus pentoxide CO2 dinitrogen pentoxide dihydrogen monoxide

  3. Prefixes – Binary Molecular Compounds Greek Prefixes for Two Nonmetals Number Indicated Prefixes 1 mono- 2 di- 3 tri- 4 tetra- 5 penta- 6 hexa- 7 hepta- 8 octa- 9 nona- 10 deca-

  4. Binary Molecular Compounds N2O dinitrogen monoxide N2O3dinitrogen trioxide N2O5dinitrogen pentoxide ICl iodine monochloride ICl3 iodine trichloride SO2 sulfur dioxide SO3 sulfur trioxide

  5. Naming Binary Compounds Binary Compound? Yes Metal Present? No Yes Type III Use Greek Prefixes Does the metal form more than one cation? No Yes Type II Determine the charge of the cation; use a Roman numeral after the cation name. Type I Use the element name for the cation. Zumdahl, Zumdahl, DeCoste, World of Chemistry2002, page 98
