If we consider the periodic table, the elements that would fall in the group 2 of the table are usually known as alkali earth metals. 20. The alkaline earth metals arranged in a row. Although pure calcium doesn’t exist in nature, calcium compounds are very common in Earth’s crust and in sea water. caesium. For example, lithium forms a stable nitride, a property common among all the alkaline earth metals (magnesium's group) but unique among the alkali metals. And all alkaline earth metals have two outer electrons. English examples for "alkaline earth metals" - The alkaline earth metal calcium is also present in significant quantity. This gives alkaline earth metals the largest atomic radii in their periods. All the alkaline earth metals have two electrons in their valence shell, so they lose two electrons to form cations with a 2+ charge.
