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.
Naturally occurring barium (56 Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001. [4]
Barium sulfide is the inorganic compound with the formula Ba S. BaS is the barium compound produced on the largest scale. [3] It is an important precursor to other barium compounds including BaCO 3 and the pigment lithopone, ZnS/BaSO 4. [4] Like other chalcogenides of the alkaline earth metals, BaS is a short wavelength emitter for electronic ...
Barium borate is an inorganic compound, a borate of barium with a chemical formula BaB 2 O 4 or Ba(BO 2) 2. It is available as a hydrate or dehydrated form, as white powder or colorless crystals. The crystals exist in the high-temperature α phase and low-temperature β phase, abbreviated as BBO ; both phases are birefringent , and BBO is a ...
Each Ba 2+ center is bound by two water ligands and six hydroxide ligands, which are respectively doubly and triply bridging to neighboring Ba 2+ centre sites. [4] In the octahydrate, the individual Ba 2+ centers are again eight coordinate but do not share ligands. [5] Coordination sphere about an individual barium ion in Ba(OH) 2.H 2 O.
