answered-by-expert Expert Answer
Elements of group 1 are called alkali metals, and elements of group 2 are called alkaline earth metals.
 
Group 1 elements are called alkali metals because they form hydroxides on reaction with water and are strongly alkaline in nature.
 
Group 2 elements are called alkaline earth metals because their oxides and hydroxides are alkaline in nature, and these metal oxides are found in the earth’s crust.
