  1. Various physical and chemical properties of barium are listed in Table 2. Barium is a lustrous, silvery metal that is relatively soft (Mohs hardness of 1.5). It crystallizes in a body-centered cubic lattice with a = 5.028 Å. It readily oxidizes when exposed to air, and must be protected from oxygen during storage.

    Barium is a chemical element; it has 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 barite (barium sulfate, BaSO 4) and witherite (barium carbonate ...

  4. Atomar Properties of Barium. Atomic number Z 56 = number of protons Standard Atomic Weight 137.327 (7) Electron configuration of Barium. Shorthand electron configuration of Barium: [Xe] 6s2 . Ionization Energies of Barium.

  5. The chemical properties of barium are predominantly shaped by its electron configuration, which accounts for its high reactivity and its predominant +2 oxidation state. Its compounds find a variety of uses in different industries, including healthcare, manufacturing, and pyrotechnics.

  6. Barium is the 56th element in the periodic table and has a symbol of Ba and atomic number of 56. It has an atomic weight of 137.327 and a mass number of 138. Barium has fifty-six protons and eighty-two neutrons in its nucleus, and fifty-six electrons in six shells. It is located in group two, period six and block s of the periodic table.

  7. Chemical properties. Barium chemically resembles, magnesium calcium and strontium but is more reactive. Reaction with chalcogens are highly exothermic. It combines easily with oxygen, the halogens, and other non-metals also reacts with water and most acids.
