In the early 1600s, a shoemaker called Vincenzo Casciarolo discovered some pebbles near the mountains of Bologna, Italy. When, Where, and How was Barium Discovered Journal of Inorganic and Nuclear Chemistry, 17(3–4), 215–221.Origin of its Name: Its name is derived from the Greek word ‘barys’ which means heavy. Electronegativity values from thermochemical data. Recommended values of temperature on the International Temperature Scale of 1990 for a selected set of secondary reference points.

Interpreting and propagating the uncertainty of the standard atomic weights (IUPAC Technical Report). Barium sulfate is used in making glass, rubber, drilling fluids, etc.Barium has an ability to absorb X-rays, so it is also used in X-rays absorber.Various engine parts like spark plug, bearings, etc contain barium metal as an alloying element.Barium nitrate and barium chlorate can produce green color, so they are used in fireworks.Barium is highly reactive to oxygen and because of this reason, barium is used to remove the oxygen gas present in the vacuum tubes.Here are some uses of the barium element. Barium reacts with oxygen to form barium oxide.There are 2 valence electrons in barium and it loses these 2 valence electrons to become stable.Barium reacts with water to form barium hydroxide.Barium is a reactive metal and because of this reason, it is always found as a compound with other elements.The barium has a density of 3.51 g/cm 3 and its atomic mass is 137.33 amu.There are many isotopes of barium, and out of those isotopes, the most abundant isotope is 138Ba. ![]()
