Lesson Topic
polyatomic ion fomulas
Lesson Outline
Review definition of polyatomic ions.
Using table of polyatomic ions, their chemical names and charge, demonstrate in precise steps the method used to write the correct chemical ionic formula for the compound formed between some typical cations and polyatomic anions.
Distribute HW sheet and work a few typical examples of the way to form, and correctly write, the ionic formulas.
Indicate the correct chemical names along with the common name ofter used.

Lesson Comments
After working a few examples with hydrogen as the cation, and indicating the common name for those compounds formed (hydrochloric acid, sulfuric acid, phosphoric acid), Ben asked a very insightful question. Why do all these acids have hydrogen as their positive ion?
