Answer 2

Explanation:

The alkaline earth metals are all of the elements in the second column (column 2A) of the periodic table. This group includes beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Alkaline earth metals have only two electrons in their outermost electron layer.

Alkaline earth metals get the name 'alkaline' because of the basic nature of the compounds they form when bonded with oxygen.
