Greater the lattice energy, greater the strength of ionic bond. It follows, therefore, that the greater the lattice energy, numerically, the greater the energy required to break up the crystal into its constituent ions. In this way it is seen that the lattice energy is the same in magnitude as, but opposite in sign to, the energy of dissociation of the crystal.

That is, from separated ions free from any solvent. The lattice energy is the change in energy that occurs when an ionic solid is separated into isolated ions in the gas phase.ДЄnother definition of the lattice energy is to regard it as the energy of formation of a given quantity of the crystal, e.g., 1 mole, from gaseous ions. The decrease in energy accompanying the process of bringing the ions, when separated from each other by an infinite distance, to the positions they occupy in the stable lattice. The energy released when a crystalline solid forms from ions is related to the lattice energy of the solid. The positive and negative ion in an ionic crystal are held together by electrostatic forces. Introduction of Lattice Energy Lattice energy, also called lattice enthalpy, of an ionic solid/crystal is a measure of the strength of bonds in that ionic compound.

The exothermic and spontaneous formation of ionic solids can be understood in terms of a Hesss Law cycle called the Born-Haber cycle. 13For cycle 3 set up the Born-Haber cycle to find lattice energy using known energy values as before. The Born-Haber Cycle shows the energies required and released when elements like Mg and Cl2 are converted into their ionic form.
