Bismuth: the essentials

Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (that is, the greatest increase in electrical resistance when placed in a magnetic field).

Bismuth: historical information

Bismuth was discovered by Known since ancient times at no data in not known. Origin of name: from the German word "bisemutum".

In early times bismuth was confused with tin and lead. So although bismuth had been discussed many times before, Claude Geoffroy the Younger showed it to be distinct from lead in 1753.

Isolation

Isolation: it is not normally necessary to make bismuth in the laboratory as it is available commercially. Bismuth is found in nature largely as bismite (Bi2O3), bismuthinite (Bi2S3), and bismutite [(BiO)2CO3]. However it is generally made as a byproduct of copper, lead,tin, silver, gold, and zinc plants. The final step involves a reduction of the oxide by charcoal.
