Molecules, being in general non-spherical, cannot simply be assigned radii, but mean radii can be assigned to them from their experimentally determined "collision diameters"
Most of the information on the sizes of ions comes traditionally from the study of such solids, following the observation that the interionic distantces Dion-ion in their crystals are additive in terms of the contributions of the cation and the anion.
it is not immediately obvious that the radii of ions that were establised in crystalline compounds, whether on the basis of interionic distances Dion-ion or on the basis of theirmochemical data, are also applicable to ions in liquid solutions.
