The lattice energy

The lattice energy is the energy necessary in order to decompose, at the temperature T=0 K, an ionic crystal in its fundamental atomic component by carrying them at a distance infinite.

The calculation of the Madelung constant

The total Coulomb interaction energy of a crystal is given by the sum of the single pair interaction terms: for ions with charges qA and qB and distance rAB.  The sum is extended to all pairs of ions present in … Continue reading
