They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery - white, somewhat reactive metals at standard temperature and pressure . </P> <P> Structurally, they have in common an outer s - electron shell which is full; that is, this orbital contains its full complement of two electrons, which these elements readily lose to form cations with charge + 2, and an oxidation state of + 2 . </P>
