The lattice energy of an ionic compound is the enthalpy change which occurs when one mole of an ionic compound dissociates into its ions in gaseous state. ... In MgO, the ionic bond is stronger than in NaCl because of more charge on the ionic species in the former (Mg+2 and O2- as compared to Na+ and Cl-)
