Section 4.1

Naming Binary 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

Section 4.1

Naming Binary Compounds

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.

Naming Binary Compounds

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.

Section 4.2

Naming and Writing Formulas for More Complex Compounds

A. Naming Compounds That Contain Polyatomic Ions

• Polyatomic ions are charged entities composed of several atoms bound together.

• They have special names and must be memorized.

Section 4.2

Naming and Writing Formulas for More Complex Compounds

A. Naming Compounds That Contain Polyatomic Ions

• Naming ionic compounds containing polyatomic ions follows rules similar to those for binary compounds. Example: ammonium acetate
