Bonding

Objectives:1. I can estimate if a bond will be ionic or covalent 2. I can model an ionic and covalent bond.3. I can explain common properties of ionic and covalent substances.4. I can write ionic unit formulas and name ionic substances.5. I can write binary molecular formulas and name binary molecular substances.6. I can identify a substance as being an acid.7. I can write the unit formula and name acids.
