CHM 1045 HANDOUT #1 – Naming chemical compounds 1) Names and symbols of the elements . You are expected to know the names and symbols for the elements of the first six periods of the periodic table, including transition metals (elements from 1-56, 72- 86), and uranium (element 92). 2) Naming ionic compounds . a) [Main group metal (1A, 2A, aluminum (3A) metals)] + [main group nonmetal]: name of metal + name of nonmetal + ide Example: CaF 2 is calcium fluoride, Li 3 P is lithium phosphide, Al 2 S 3 is aluminum sulfide b) [Transition group metal (or group 4A metal, or Tl)] + [main group nonmetal]: name of metal (charge of metal) + name of nonmetal + ide Example: Cu 2 O is copper (I) oxide, CuO is copper (II) oxide, SnF 2 is tin (II) fluoride Note: There are a few transition metals that almost always have a particular charge, such as silver, which almost always forms the Ag + ion. In those cases the charge of the metal can be omitted. However, for this class we will always give the charge as a Roman numeral for compounds in category 2b. c) Cation group (NH 4 + is the only common cation group, and is called ammonium ion) Example: NH 4 Br is ammonium bromide d) Anion group PO 4
