Question

explain why the atomic and ionic radii of the alkaline earth metal are lower as compared to alkali metal . how does they differ from alkali metal based on the above observation?​

Answer 1

Explanation:

Because of their higher positive charge (+2) and smaller ionic radii, the alkaline earth metals have a much greater tendency to form complexes with Lewis bases than do the alkali metals. This tendency is most important for the lightest cation (Be 2+) and decreases rapidly with the increasing radius of the metal ion.
