Which statement is true about crystal lattice energy?
It increases as the size of the ions increases.
It increases as the charge on the ions decreases.
It is the energy that ions absorb when they form a crystal.
It is a measure of the strength of the bonds between ions.

Lattice energy is defined as amount of energy released on the formation of one mole of crystalline solid from gaseous ions.It is also defined as energy required to break the 1 mole of crystalline solid into its constituting ions in gaseous state that is strength between the ions.

It depends upon two factors:

With increase in charge on the ion the lattice energy increases.
With increase in the size of the ions the lattice energy decreases.

So, from the given options the correct statement is:

It is a measure of the strength of the bonds between ions.

Which statement is true about crystal lattice energy? It increases as the size of the ions increases. It increases as the charge on the ions decreases. It is the energy that ions absorb when they form a crystal. It is a measure of the strength of the bonds between ions.
