What elements make up alkaline earth metals?
What are Alkaline Earth Metals? Elements whose atoms have their s-subshell filled with their two valence electrons are called alkaline earth metals. Their general electronic configuration is [Noble gas] ns2. They occupy the second column of the periodic table and so-called as group two metals also.

alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
What are alkali metals class11?
The alkali metals are Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs) and Francium (Fr). The alkali metals react vigorously with water forming soluble hydroxides which are called alkalis. This is the reason why these metals are called alkali metals.
What are the alkali earth metals on the periodic table?
Alkaline earth metals are metals that are found in Group II of the periodic table. Six elements such as beryllium, magnesium, calcium, strontium, barium, and radium are placed in this group. These metals show resemblance to alkali metals which is why they are placed besides them in the periodic table.
Where are alkali earth metals located on the periodic table?
The alkaline earth metals are metallic elements that are found in the second vertical row of the periodic table. The alkaline earth metals get their name because of their reactive properties.
