Vedclass · Answer

(A) Among the alkaline earth metals,$Be$ (Beryllium) has a very small atomic size and high ionization enthalpy. Due to its high charge density and the availability of vacant $2p$ orbitals,it has a strong tendency to form covalent bonds and complex compounds (e.g.,$[Be(H_2O)_4]^{2+}$,$[BeF_4]^{2-}$). Other alkaline earth metals are larger and tend to form ionic compounds.
