Naming Compounds

Question 1

Formulas for ionic compounds

Answer 1

1. Write the symbol for the metal cation and its charge then the symbol for the nonmetal anion and its charge
2. adjust the subscript on each cation and anion to balance the overall charge
3. check that the sum of the charges of the cations equals the sum of the charges of the anion

Question 2

Ionic compound: Binary compounds: containing only two different elements

Answer 2

1. name of cation (metals)
2. base name of anion (nonmetal) +ide

Question 3

Ionic compound: Binary compounds: forms more than one kind of cation

Answer 3

1. name of the cation
2. Roman numeral that indicates the charge of the metal
3. Base name of anion (nonmetal) +ide

Question 4
