Objectives

You have completed this lesson when you can:

1. Describe the nature of ionic bonding and explain why it results in the formation of compounds that have network structures, not molecules.

2. Use the periodic table, our current atomic model and the octet rule to determine the charges of ions formed by the representative metals and nonmetals.

3. Use lists to determine the charges for the ions of multivalent metals.

4. Use the charges of cations and anions to determine the formulas of ionic compounds.

5. Name cations, anions and ionic compounds using the standard system of ionic nomenclature.

6. Write formulas for ionic compounds based on their names or the ions they are made up of.

7. Name and write formulas for common polyatomic ions (nitrate, chlorate, sulfate, carbonate, phosphate, acetate, hydroxide, and ammonium).
