Smallest cation in 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). Webb6 dec. 2024 · Group 1 metals are less reactive than group 2 metals. Its valence shell contains 2 electrons. They have low electronegativity. Compounds of alkali metals are often insoluble in water. Alkaline metals are usually Shiny, silvery. They have ions with a +2 charge. They are solid. They are harder, denser, stronger.
