The reason is the … Web5 mei 2024 · The ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. The trend observed in size of ionic radii is due to shielding of the outermost electrons by the inner-shell electrons so that the outer shell electrons do not “feel” the entire positive charge of the nucleus.
