Alkaline Earth metals form Group 2 of the periodic table. Except for radium, all of the elements in this group are used in commercial applications. Magnesium and calcium are two of the six most common elements on Earth, and are essential to some geological and biological processes. These elements have a shiny gray-white appearance. They are good conductors of electricity and have higher melting and boiling points than the alkali metals. Melting points range from 650° to 1,287°C and boiling points range from 1,090° to 2,471°C.More

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).[1] The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.[2] Structurally, they (together with helium) have in common an outer s-orbital which is full;[2][3][4] that is, this orbital contains its full complement of two electrons, which the alkaline earth metals readily lose to form cations with charge +2, and an oxidation state of +2.[5] All the discovered alkaline earth metals occur in nature, although radium occurs only through the decay chain of uranium and thorium and not as a primordial element.[6] There have been experiments, all unsuccessful, to try to synthesize element 120, the next potential member of the group.
