About
The bond between cations and anions. Occurs when there is large electronegativity. Must remember Polyatomic Ions
Ionic lattices
Enthalpy: Total chemical potential energy in a system Lattice enthalpy (): Enthalpy change when 1 mole of an ionic compound is broken up into scattered gaseous ions. Lower the ionic radius, greater the lattice enthalpy.
Properties
Volatility: Tendency to vaporize. Must overcome electrostatic forces. Electrical conductivity: Ability to conduct electrical current. Must have mobile electrons. Solubility: Ability to be dissolved. Solvent must be polar. Brittle: Applied forces peels the layer using repulsive forces between different charged ions. Alloys prevent this.
