- The ionic radius is the distance of the outermost shell of electrons from the nucleus of an ion. It indicates the size of an ion in a crystal lattice where two atoms are bonded by an ionic bond. The ionic radius is analogous to the atomic radius of an atom [1-4].www.chemistrylearner.com/the-periodic-table/ionic-radius
