For 10 points, name this quantity denoting the strength of bonds in an ionic solid, which is also the amount of energy needed to separate the molecules of a crystal into an ionic gas.
This quantity can be calculated using the Kapustinskii equation, and a constant proportional to this quantity can be calculated using the Ewald method and is named for Madelung. Another method for finding it involves the reciprocal of an exponent that falls between 5 and 12 and is named for (*) Born and Lande. This quantity can be determined experimentally using a method that atomizes a substance to measure enthalpy, the Born-Haber cycle.
