An element family is a set of elements sharing common properties. Elements are classified into families because the three main categories of elements metals, nonmetals, and semimetals are very broad.The characteristics of the elements in these families are determined primarily by the number of electrons in the outer energy shell. Group 2A or IIA of the periodic table are the alkaline earth metals: beryllium Be, magnesium Mg, calcium Ca, strontium Sr, barium Ba, and radium Ra.They are harder and less reactive than the alkali metals of Group 1A. The name comes from the fact that the oxides of these metals produced basic solutions when dissolved in water, and they remained solids at the temperatures.
