<P> Barium is a chemical element with 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 . Its hydroxide , known in pre-modern history as baryta , does not occur as a mineral , but can be prepared by heating barium carbonate . </P>
