Journal Entry:

These cards show a sodium ion and three polyatomic ions. What do you think a polyatomic ion is? Name three compounds formed between sodium ions and each of the three polyatomic ions. Use the rule of zero charge to write the compounds formulas.

Learning Intentions

• We will learn how to recognize and name polyatomic ions

• We will learn the difference between polyatomic and monatomic ions.

• We will learn how to write names and chemical formulas of compounds with polyatomic ions. 

Closing Task:

You can name compound with a polyatomic ion in it and identify what ions are present as well as the charges on the ions.
