An estimate of the strength of the bonds in an ionic compound can be obtained by measuring the lattice energy of the compound, which is the energy given off when oppositely charged ions in the gas phase come together to form a solid.

The Lattice energy, U, is the amount of energy requried to separate a mole of the solid (s) into a gas (g) of its ions. ... As defined, the lattice energy is positive, because energy is always required to separate the ions. For the reverse process, the energy released is called energy of crystallization, Ecryst.

The lattice energy is the energy associated with the chemical reaction of gaseous ions combining to form 1 mole of a solid ionic compound. This value cannot be determined directly. However, related equations with energy values that can be determined directly can be summed to get the value for lattice energy.
