Define lattice energy?

Expert Answer
Lattice energy is the measure of the forces of attraction between the ions. It is defined as the amount of energy required to break one mole of a crystal into its free ions.
The larger the forces of attraction, the greater will be lattice energy. The lattice energy also depends upon the size of the ion and its charge. For the cation of same valency, ionic solids having the same anion will display a decrease in the lattice energy with increase in size of the cation. This is due to decrease in forces of attraction between them.
