Entry: alkaline earth metal

URI: http://registry.it.csiro.au/def/environment/object/alkaline_earth_metal

A group of chemical elements in the periodic table with very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure and readily lose their two outermost electrons to form cations with charge +2. In the modern IUPAC nomenclature, the alkaline earth metals comprise the group 2 elements. The alkaline earth metals are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). This group lies in the s-block of the periodic table as all alkaline earth metals have their outermost electron in an s-orbital.
