In 1918 Max Born and Alfred Landé proposed that the lattice energy could be derived from the electrostatic potential of the ionic lattice and a repulsive potential energy term. :$E\; =-\; \backslash frac\backslash left(1-\backslash frac\backslash right)$ where: *''N''A = Avogadro constant; *''M'' = Madelung constant, relating to the geometry of the crystal; *''z''+ = charge number of cation *''z''− = charge number of anion *''e'' = elementary charge, 1.6022 C *''ε''0 = permittivity of free space *:4π''ε''0 = 1.112 C2/(J·m) *''r''0 = distance to closest ion *''n'' = Born exponent, typically a number between 5 and 12, determined experimentally by measuring the compressibility of the solid, or derived theoretically. ==Derivation== The ionic lattice is modeled as an assembly of hard elastic spheres which are compressed together by the mutual attraction of the electrostatic charges on the ions. They achieve the observed equilibrium distance apart due to a balancing short range repulsion. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Born–Landé equation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
