Ionic radius - Wikipedia

Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres with radii such that the sum of ionic radii of the ion and anion gives the distance between the ions in a crystal lattice.Ionic radii are typically given in units of either picometers (pm) or
