Question

Why do reactions of the alkaline earth metals differ from those of the Group 1 metals?

Answer 1

hope this will help you

Step-by-step explanation:

alkaline earth metals have two valance electrons whereas group 1 metals(Alkali metals) have one valance electrons.so, it takes more energy to remove two valance electrons from an atom than one valance electrons.therefore the reactions of the alkaline earth metals are differ from those of the group 1 metals( Alkali metals).

Answer 2

Alkaline earths have larger lattice energies than alkali metals due to small size and high charge. Hence, alkaline earth metal hydroxides have lower solubility than alkali metals.
