Naming Binary and Complex Compounds

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

Objectives

1.  AxBy where A is a metal, B is a non-metal

2.  CxDy where C and D are non-metals

Chapter 4

Naming Binary and Complex Compounds 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

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.

Objectives

Chapter 4

Naming Binary and Complex Compounds

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.
