1. Lattice energy can be defined as the enthalpy of formation for ions of opposite charge in the gas phase to be changed into a solid.

2. Entropy is a thermodynamic measure of the disorder in a system. Denoted by symbol S.

3. Enthalpy of atomization is the amount of enthalpy change when a compound's bonds are broken and the component atoms are reduced to individual atoms.

4. A reaction that occurs in a given set of conditions without intervention. A spontaneous reaction proceeds to completion without any outside help. The equation for spontaneity is

ΔG = Δ H - TΔS
