Barium is a soft, silvery-white metal, with a slight golden shade when ultrapure. [9]: 2 The silvery-white color of barium metal rapidly vanishes upon oxidation in air yielding a dark gray layer containing the oxide. Barium has a medium specific weight and high electrical conductivity. Because barium is difficult to purify, many of its ...
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 chlorate, Ba(ClO 3) 2, is the barium salt of chloric acid. It is a white crystalline solid , and like all soluble barium compounds, irritant and toxic. It is sometimes used in pyrotechnics to produce a green colour .
Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates , it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite .
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water. It occurs in nature as the mineral barite, which is the main commercial source of barium and materials prepared from it. Its opaque white appearance and its high density are exploited ...

There are several elements that are not used by mammals, but seem to be beneficial in other organisms: boron, aluminium, titanium, arsenic, rubidium, strontium, cadmium, antimony, tellurium, barium, the early lanthanides (from lanthanum to gadolinium), tungsten, and uranium. (In the cases of Al and Rb the mechanism is not well understood.)
Years later, Keeler claims Cleary sent her chilling messages on Facebook admitting to the sexual assault. "So I raped you,” Cleary allegedly wrote, per the affidavit.
