1. Formation of Ionic Bonds

2. Ionic Bonds
Ionic bond is an electrostatic force that holds oppositely charged ions together.
“Opposites attract” & form an ionic bond.

3. Ionic Bonds Binary Ionic Compounds
Formed from two parts (binary): a metallic cation and a non-metallic anion.
Metal + Oxygen = oxide
Metal + other non-metal = salt

4. Ionic Bonds Physical Properties:
Form a crystal lattice (represented by a formula unit)
Have high Melting Point & Boiling Point.
Hard & brittle
Poor conductors (as a solid).

5. Ionic Bonds Physical Properties:
Good conductor when dissolved in water (aqueous solution)
Ionic salt whose aqueous solution conducts electricity is an electrolyte.
