WebbThe Size of a Cation is always smaller than its parent atom. Why? The ionic radius of a cation is smaller than the atomic radius of the element from which it is derived. Reason: This is due to the reason that with the successive loss of electrons, the nuclear charge attracts the remaining electrons with a greater. Webb6 nov. 2024 · When electrons are removed from an atom, it might lose its outermost electron shell, making the ionic radius smaller than the atomic radius. In contrast, some atoms are more stable if they gain one or more electrons, forming an anion or negatively charged atomic ion. Examples include Cl - and F -. Webb4 apr. 2024 · Cause of Lanthanide Contraction. The effect of lanthanide contraction results from the poor shielding of nuclear charge (with the attractive nuclear force on electrons) by 4f electrons; the 6s electrons can be drawn towards the nucleus, hence resulting in the smaller atomic radius. In the case of single-electron atoms, the average separation of ... kiss my face products canada
