83 - Bismuth post-transition metal

Discovered by Claude François Geoffroy in 1753

Bismuth

Bismuth is a chemical element with symbol Bi and atomic number 83. Bismuth, a pentavalent post-transition metal, chemically resembles arsenic and antimony. Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores.
