Question

State any one reason for alkaline earth metals having greater tendency to form complexes than alkali metals

Answer 1

They are less electropositive or metallic than the alkali metal. Reason: Due to low ionisation energies, the alkaline earth metals have a strongtendency to lose both the valence electrons to form dipositive cations. ... On moving down the group, the atomic radii increases and ionization enthalpy decreases
