Alkaline earth metal - Wikipedia

The alkaline earth metal salts are generally described as “sparingly soluble” in water, and so these salts will precipitate out of the solution and form a white powder. The extra hydrogen atoms, meanwhile, find each other agreeable to bond with and make H2, and then bubble out of the solution as hydrogen gas.

Alkaline Earth Metals - Study Material for IIT JEE | …

The name alkaline earth metals was given to magnesium, calcium, barium & strontium since their oxides were alkaline in nature and these oxide remained unaffected by heat or fire and existed in earth. So, group 2 metals are called alkali earth metals because their hydroxides are strong alkali (just like those of alkali metals) plus these all are found in earth crust.
