Abstract:
Expectation values for size differences between pairs of "ions" (atoms in oxidation states =/= 0) embedded into similar coordination environments are calculated from tables of bond-valence parameters and ionic radii.

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
