Because of its high chemical reactivity, barium is never found in nature as a free element. The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium).

Barium itself tends to have relatively few commercial uses. However, its compounds have a wide variety of applications in industry and medicine. Barium sulfate is used in X-ray studies of the gastrointestinal (GI) system. The GI system includes the stomach, intestines, and associated organs. Ba – Barium Introduction Barium is a member of group 2 elements of the periodic table, along with Be, Mg, Ca and Sr, which are all highly electropositive metals. The element has an atomic number of 56, an atomic mass of 137, one oxidation state (+2), and seven naturally occurring isotopes (130Ba, 132Ba and 134Ba to 138Ba), of which 138Ba is of Cs-137 according to the scheme shown in Figure 2.

Finally, Ba-138 has been used in studying so-called r- and s-processes in stars. 2021-01-13 barium (Ba) [bar´e-um] a chemical element, atomic number 56, atomic weight 137.34.
