Question

Why the elements of group 2 are called alkaline earth metals?

Answer 1

The elements of the group 2 of periodic table forms basic(alkaline) hydroxides when they react with water.So they are called as alkaline metals.

And all of them are available in nature(not anyone is synthetic)So they are called as earth metals.

For the above two reasons we call them as alkaline earth metals.
