Answer:
The ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. ... When an electron is added to an atom, forming an anion, the added electron repels other electrons, resulting in an increase in the size of the atom.

Explanation:
Ionic radius (rion) is the radius of an ion, regardless of whether it is an anion or a cation. Although neither atoms nor ions have sharp boundaries, it is useful to treat them as if they are hard spheres with radii.
