Who discovered it?Carl Wilhelm Scheele (9 December 1742 – 21 May 1786) was a Swedish Pomeranian pharmaceutical chemist. Scheele discovered organic acids tartaric, oxalic, uric, lactic, and citric, as well as hydrofluoric, hydrocyanic, and arsenic acids.

BaruimBarium is a chemical element with symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal. Because of its high chemical reactivity barium is never found in nature as a free element. Its hydroxide was known in pre-modern history as baryta; this substance does not occur as a mineral, but can be prepared by heating barium carbonate.

More information on Barium... This mineral attracted attention in the 17th century, when it was found to radiate red light after heating. The element was called barium because it was found in barite (barium sulfate) a mineral given its name because of its high density. The Greek ‘barys’ means heavy.Barium is most commonly found as the mineral barite (BaSO4) and witherite (BaCO3) and is primarily produced through the electrolysis of barium chloride (BaCl2). Barium is used in fireworks to give them that green color.
