Properties of the Alkaline Earth Metals

Alkaline Earth Metals-- Alkaline earth metals are found in group 2 of the periodic table
They include beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra)
The alkaline earth metals share several common properties, they have
Low density
Silver and soft metals
Ductile and malleable
React with halogens and water
Alkaline earth metals are reactive, not as reactive to alkali metals, but still very reactive. This is because they all contain two electrons in their outer shell. Because they are reactive they are usually found in nature in compound form.

Strontium compounds are often added to fireworks displays for their red flame test color.
Calcium is used by our body for our teeth and bones.
Magnesium is used in antacid and barium is used in light bulbs.
So there are the group 2 alkaline earth metals. They each have two valence electrons.
