What is lattice energy

Solution

Lattice energy is the energy required to break an ionic crystal into its constituent ions. The same amount of energy is released when one gram molecule of the crystal is formed from gaseous ions. The lattice energy of an ionic solid is a measure of the strength of bonds in that ionic compound.
