Bonding

Revision

             Learning Intention: 

What? We are learning  how to write the names and chemical formulas for ionic bonds. 

Why?  In order to  use the International Union of Pure and Applied Chemistry (IUPAC) nomenclature correctly. 

             Success Criteria

I can: 

- Identify the properties of ionic bonds.

-Develop formulas for ionic bonds

- Identify the IUPAC nomenclature for ionic bonds when given an ionic compound formula.
