Bismuth was not mined as ore but appears to have occurred as the native … In oxidation state +3, bismuth forms trihalides with all of the halogens: BiF 3, BiCl 3, BiBr 3, and BiI 3. All of these except BiF 3 are hydrolyzed by water. Bismuth(III) chloride reacts with hydrogen chloride in ether solution to produce the acid HBiCl 4. The oxidation state +5 is less frequently encountered. One such … See more Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic See more Bismuth metal has been known since ancient times and it was one of the first 10 metals to have been discovered. The name bismuth dates to around 1665 and is of uncertain etymology. The name possibly comes from obsolete German Bismuth, Wismut, … See more Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements. Oxides and sulfides See more Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials.
