Depending on the naming system group 2 or IIA elements are the second collumn of the periodic table. There are 18 groups, 3-12 comprise the transition metals. Group 1 are the alkali metals and IIA or 2 is the alkali earth metals. The horizontal rows are the periods, so Magnesium calcium and strontium belnog to the same group but different periods. Each group share simlar characteristics based on their chemical properties; most notably they all have two valence electrons in their outermost shells.
