WebIonic radius is defined as the total distance between the outermost shell electron and the nucleus of a particular anion or cation. As there is an addition of electrons to an atom the size of... 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.
