WebThe radius of an ion, whether anion or cation, is called the ionic radius (rion). Although atoms and ions do not have specific borders, it is beneficial to treat them as spherical particles with radii. The spacing between ions in a crystal lattice can be calculated by adding the ionic radii of a cation and an anion.
