Lattice energy is a measure of the stability of a solid ionic compound. It is defined as the energy required to break apart one mole of a solid ionic compound into its constituent ions in the gas phase.
The lattice energy depends on the charges of the ions and the distances between them. As the size of the ions increases, the distance between them also increases. This leads to a decrease in the lattice energy. A lower lattice energy means weaker attractions between the ions, which in turn leads to a lower melting point.
Similarly, a lower lattice energy also makes the compound more soluble in water, as weaker attractions between ions make it easier for water molecules to surround and dissolve the ions. Therefore, understanding the relationship between lattice energy and size is crucial in predicting the melting points and solubilities of ionic compounds.
