complete the sentences regarding alkaline earth metals

Answer 1

Compared to cosresponding Group IA elemenents, Group 2A elements have higher metallic bonding and smaller atomic sizes which makes them harder and less denser than alkali metals. Group 2A elements have smaller atomic radie and higher ionization energy thay Group I A elemento I earth Like alltali metals, the alkaline wnetals are Strong reducing agents. Group 2A Salts have much higher lattice energies than Group 1 A (1) salt because the 2A Cations are & Smaller and have twice the charge, resulting in much higher charge densities and higher Solubilities for 2A sobebilities. Salts.
