The ionic radii decrease by ca. 20% from La3+ to Lu3+ (Table 1.1, values for 8-coordination18). It arises through inadequate screening of the nuclear charge As the number of f electrons increases, there is an increase in the effective nuclear charge leading to a progressive reduction in the Ln3+ size.
Key Points. The ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. When an atom loses an electron to form a cation, the lost electron no longer contributes to shielding the other electrons from the charge of the nucleus; consequently, the other electrons are more strongly attracted to the nucleus, and the radius of the atom gets smaller.

This means the outer electron in krypton forms a stronger electrostatic force of attraction with the positive nucleus- making its ionic radius smaller than that of rubidium. Despite rubidium's greater nuclear charge, the higher shielding effect is the reason why it has a smaller ionic radius than krypton

I understand that ionic radius increases as you go down the periods but what about ions?? The more + the charge, the smaller the ionic radius. Remember that - means adding electrons. These electrons go in the outermost shells.
Jul 26, 2009 · This is basically a comparison of atomic radius and ionic radius. Since the Sodium loses an electron to form its cation.

Atomic 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). Similar trends are observed for ionic radius, although ... Nov 27, 2020 · Covalent Radius: Covalent radius is defined as one half of the distance between the centres of the two similar nuclei of two similar atoms bonded together by a single covalent bond. For e.g. the distance between two oxygen atoms in molecular oxygen is 132 pm. Hence crystal radius of oxygen = 132 / 2 = 66 pm. Covalent radii are additive. The ionic radii of cations and anions are always smaller or larger, respectively, than the parent atom due to changes in electron-electron repulsions, and the trends in ionic radius parallel those in atomic size.
