1. Aim: How to distinguish between ionic and covalent bonding?
Two major categories of compounds are ionic and molecular (covalent) compounds.
Metals tend to react with nonmetals to form ionic compounds.
Nonmetals tend to react with other nonmetals to form molecular (covalent) compounds.
Ionic compounds containing polyatomic ions have both ionic and covalent bonding.

2. Aim: How to distinguish between ionic and covalent bonding?
Essential questions:
Compare and contrast ionic and covalent bond types.
Draw Lewis structures (electron dot diagrams) for atoms, ions and compounds.
Determine the noble gas configuration an atom will achieve when bonding.
Use the electro negativity difference ( EN) to determine bond type (ionic, polar covalent, or non-polar covalent.)
