Because of its high chemical reactivity, barium is never found in nature as a free element This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Barium mineral species. Strontium. Barium chloride is quite soluble in water (as is the case with most ionic salts). Commercially, it is made on small scale by the electrolysis of molten barium chloride, BaCl 2. cathode: Ba 2+ (l) + 2e-Ba anode: Cl-(l) 1 / 2 Cl 2 (g) + e-Barium metal can also be islated from the reduction of barium oxide, BaO, with aluminium. Xenon (symbol: Xe) is an element (noble gas) with atomic number 54, which means it has 54 protons and 54 electrons. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal.
