Nomenclature Naming System

This guide explores the nomenclature of anions and binary compounds, focusing on the naming conventions for ionic compounds with fixed and variable charge metals. Learn how to name compounds like sodium chloride (NaCl) and iron (III) chloride (FeCl3) using Roman numerals for transition metals. Additionally, the basics of molecular nomenclature, including the use of prefixes for naming molecular compounds, are covered. Additionally, it highlights the seven diatomic elements essential for understanding chemical formulas.

  1. NomenclatureNaming System

  2. Endings of Anions (-ide)

  3. Contain 2 different elements • Name the metal first, then the nonmetal as -ide. • Use name of a metal with a fixed charge Groups 1A, 2A, 3A and Ag, Zn, and Cd Examples: NaCl sodium chloride ZnI2 zinc iodide Al2O3 aluminum oxide

  4. Common transition metals

  5. Complete the names of the following binary compounds: Na3N sodium ________________ KBr potassium ________________ Al2O3 aluminum ________________ Fe2S _________________________

  6. Naming w/ transition metals Use a roman number after the name of a metal that forms two or more ions Transition metals and the metals in groups 4A and 5A FeCl3(Fe3+) iron (III) chloride CuCl (Cu+ ) copper (I) chloride SnF4 (Sn4+) tin (IV) fluoride PbCl2 (Pb2+) lead (II) chloride Fe2S3(Fe3+) iron (III) sulfide

  7. Practice problems Complete the names of the following binary compounds with variable metal ions: FeBr2 iron (_____) bromide Cu2O copper (_____) oxide SnCl4 ___(_____ ) ______________ FeO ________________________ CuS ________________________

  8. Molecular Nomenclature PREFIX mono- di- tri- tetra- penta- hexa- hepta- octa- nona- deca- NUMBER 1 2 3 4 5 6 7 8 9 10

  9. Molecular Nomenclature • CCl4 • N2O • SF6 • carbon tetrachloride • dinitrogen monoxide • sulfur hexafluoride

  10. C. Molecular Nomenclature • The Seven Diatomic Elements Br2 I2 N2 Cl2 H2 O2 F2 H N O F Cl Br I
