Bismuth had been identified in the fifteenth century but it was not until the work of Claude Geoffroy the Younger who identified Bismuth as its own element and different from lead. Bismuth while a stable metal does exhibit some radioactive properties over time. It is a brittle crystalline metal and can repel magnetic fields. It also has a high conductivity of electricity. Bismuth is used in medicine and cosmetics. It is a solid metal at room temperature with a melting point of 271°c and a boiling point of 1564°c.
Known to the ancients.
Main use is in pharmaceuticals and low melting point alloys used as fuses.
It can be found free in nature and in minerals like bismuthine (Bi2O3) and in bismuth ochre (Bi2O3)
