Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice. Ionic radii are typically given in units of either picometers (pm) or angstroms (Å), with 1 Å = 100 pm. Typical values range from 31 pm (0.3 Å) to over 200 pm (2 Å).

WebIonic radii definition. An ion is an atom that has acquired an electrical charge by gaining or losing one or more electrons. The size of a spherical ion is measured by the ionic radius of the ion (ion) of an atom (either a cation or anion). WebIonic Radii and Isoelectronic Series An ion is formed when either one or more electrons are removed from a neutral atom to form a positive ion (cation) or when additional electrons attach themselves to neutral atoms to form a negative one (anion). floating toys for babies
