Ionic radius - Wikipedia
https://en.wikipedia.org/wiki/Ionic_radius
WEBIonic 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 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 .

WEBIonic radii follow the same vertical trend as atomic radii; that is, for ions with the same charge, the ionic radius increases going down a column. The reason is the same as for atomic radii: shielding by filled inner shells produces little change in the effective nuclear charge felt by the outermost electrons.

WEBIonic radii depend on oxidation state (higher charge => smaller cation size, larger anion size) We can build up a table of ionic radii by assuming that the bond length is the sum of the radii (r + + r -) if the ions are in contact in the crystal. Consider for example the compounds MgX and MnX, where X = O, S, Se.

WEBAtomic and ionic radii are found by measuring the distances between atoms and ions in chemical compounds. On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing number of electron shells).

WEBJan 1, 2018 · The ionic radius of the ion (r ion) of an atom (either a cation or anion) is a measure of the size of a spherical ion. The ionic radius is similar to but different from the atomic radius for the ionic size is dependent on the distribution of its outermost electrons and is inversely proportional to the effective nuclear charge experienced by ions.

WEBIonic radius is the distance from the nucleus of an ion up to which it has an influence on its electron cloud. Ions are formed when an atom loses or gains electrons. When an atom loses an electron it forms a cation and when it gains an electron it becomes an anion.
