How are ionic radii measured
WebThe type of atomic radius being measured here is called the metallic radius or the … WebIonic radius increases. Ionic radius is the distance from the nucleus to the outer edge of the electron cloud of an ion. The same trend of atomic radius applies once you divide the table into metal and nonmetal sections. A cation has a smaller radius than its neutral atom because it loses valence electrons.
