For a uni-univalent ionic crystal of specified structure, the binding energy \(V_b\) per pair of ions is \(V_b = \alpha\frac{e^2}{4\pi \varepsilon_0 a}\), where \(e\) is the elementary charge, \(\varepsilon_0\) is the electric constant, and \(a\) is the lattice constant which should be specified.

"Madelung Constant" is used in determining the electrostatic potential of a single ion in a crystal by approximating the ions by point charges. It is named after Erwin Madelung, a German physicist.
