Answer:

Explanation:

The lattice energy is the energy required to dissociate one mole of an ionic compound to its constituent ions in the gaseous state. It is a measure of the cohesive forces that bind ions. Lattice energy is relevant to many practical properties including solubility, hardness, and volatility.

The two main factors affecting lattice enthalpy are the charges on the ions and the ionic radii (which affects the distance between the ions). Sodium chloride and magnesium oxide have exactly the same arrangements of ions in the crystal lattice, but the lattice enthalpies are very different.
