ionic radius, ionic radii
1. In physical chemistry, a measure used to determine the effective range of an ion in a compound, commonly based on the sum of the radii of a pair of oppositely charged ions in a crystal.
2. Radii which can be assigned to ions because the rapid variation of their repulsive interaction with distance makes them repel like hard spheres.

These radii determine the dimensions of ionic crystals.
