These atomic-ionic radii are the “realistic” radii of atoms which is suitable for describing anion-cation contacts in ionic structures. The data were derived by the comparison of bond lengths in over 1200 bond types in ionic, metallic, and covalent crystals and molecules by Slater, J. Chem. Phys., 1964, 41, 3199. In the case of He, Ne, Ar, Kr, Xe, At and Rn the radii were taken from Clementi et al., J. Chem. Phys. 1963, 38, 2686.

Note: The color code used in these models is CPK. This is the scheme conventionally used by chemists.
