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
