Formation of Ionic Bonds

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

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

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).

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