Objectives 1. To learn to name binary compounds of a metal and nonmetal 2. To learn to name binary compounds containing only nonmetals 3. To summarize the naming of all types of binary compounds 1. A x B y where A is a metal, B is a non-metal 2. C x D y where C and D are non-metals
A. Naming Compounds That Contain a Metal and a Nonmetal Binary ionic compounds contain positive cations and negative anions. Type I compounds Metal present forms only one cation Type II compounds Metal present can form 2 or more cations with different charges
A. Naming Compounds That Contain a Metal and a Nonmetal
A. Naming Compounds That Contain a Metal and a Nonmetal For compounds containing both a metal and a nonmetal, the metal is always named first. The nonmetal is named from the root element name.
A. Naming Compounds That Contain a Metal and a Nonmetal Type I Binary Ionic compounds Rules A Use your Machine to identify and name the following: NaCl, MgO, LiBr, CaF 2, Al 2 O 3
A. Naming Compounds That Contain a Metal and a Nonmetal Type II Binary Ionic compounds Since the metal ion can have more than one charge, a Roman numeral is used to specify the charge. Rules B Gold (I) Chloride Gold (III) Chloride

A. Naming Compounds That Contain Polyatomic Ions Polyatomic ions are charged entities composed of several atoms bound together ( charged molecules ). Compounds should be electrically neutral Use parentheses (when appropriate) in writing formulas e.g Ni(CN) 2 They should be considered as other ions in determining names of compounds They have special names which should be memorized.
A. Naming Compounds That Contain Polyatomic Ions Naming ionic compounds containing polyatomic ions follows rules similar to those for binary compounds. ammonium acetate Rules D
Naming Compounds That Contain Polyatomic Ions Name the following compounds (are they Type I or II metals?): - NaOH - Na 2 CO 3 - CuOH - Cu(OH) 2 - Cu 2 SO 4 - Zn(NO 3 ) 2 - Fe 3 (PO 4 ) 2 - NaC 2 H 3 O 2 - (NH 4 ) 2 CO 3
