"Web33.5. 43.5. 64.5. 67.5. 68.0. Hydration of ions: The alkali metal ions are highly hydrated. The smaller the size of the ion, the greater is the degree of hydration. Thus, Li + ion gets much more hydrated than Na + ion which in turn is more hydrated than K + ion and so on. The extent of hydration decreases down the group. " - Hydrated ion radius
