Cation vs Anion: Definition, Chart and the Periodic Table

WebbThe radius for a cation is smaller than the parent atom (Al), due to the lost electrons; the radius for an anion is larger than the parent (S), due to the gained electrons. Cations with larger charges are smaller than cations with smaller charges (e.g., V 2+ has an ionic radius of 79 pm, while that of V 3+ is 64 pm).

Webb14 nov. 2024 · The atom can be cation or anion by losing or gaining electron. When an atom loses electron sometime it has less orbital than before. However the nucleus attract the rest of the electrons more tightly towards the nucleus. The ionic radius is thus reduced than atomic radius.
