Bismuth is a chemical element with the symbol Bi and atomic number
83. It is a pentavalent post-transition metal and one of the
pnictogens with chemical properties resembling its lighter group 15
siblings arsenic and antimony. Elemental bismuth may occur
naturally, although its sulfide and oxide form important commercial
ores. The free element is 86% as dense as lead. It is a brittle
metal with a silvery white color when freshly produced, but surface
oxidation can give it an iridescent tinge in numerous colours.
Bismuth is the most naturally diamagnetic element, and has one of
the lowest values of thermal conductivity among metals.
