About Barium-137 Carbonate Isotope

Barium 137 (Barium-137) is a stable (non-radioactive) isotope of Barium. It is both naturally occurring and produced by fission. Barium 137 Carbonate is one of over 250 stable metallic isotopes produced by American Elements for biological and biomedical labeling, as target materials and other applications. Barium Carbonate is also available in ultra high purity and as nanoparticles. Barium Carbonate 137 isotopic material is generally immediately available. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement

The number of electrons in each of barium's shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s2. Barium Bohr ModelBarium is a member of the alkaline-earth metals. The barium atom has a radius of 222 pm and a Van der Waals radius of 268 pm. Barium was discovered by Carl Wilhelm Scheele in 1772 and first isolated by Humphry Davy in 1808. Elemental BariumIn its elemental form, barium is a soft, silvery-gray metal. Industrial applications for barium include acting as a "getter," or unwanted gas remover, for vacuum tubes, and as an additive to steel and cast iron. Barium is also alloyed with silicon and aluminum in load-bearing alloys. The main commercial source of barium is the mineral barite (BaSO4); it does not occur naturally as a free element . The name barium is derived from the Greek word "barys," meaning heavy.
