Question

berryllium compounds are mainly covalent where other grouo 2 compounds are predomiantly ionic. discuss the evidence for this statement ang suggest factors that contribute to it

Answer 1

Beryllium having the electronic configuration 1s²2s² almost exclusively forms covalent compounds due to its high ionization potentials and the small size. For the next compounds of group 2 the ionization potential is low comparatively so electron can be removed easily.
