Barium - Wikipedia

Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.Because of its high chemical reactivity, barium is never found in nature as a free element.. The most common minerals of barium are baryte (barium sulfate, BaSO 4) and witherite (barium carbonate, BaCO 3), both insoluble in water.
