It is a white, crystalline, brittle metal with a pinkish tinge. It occurs in a native state. 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 (i.e., greatest increase in electrical resistance when placed in a magnetic field).
Melting point: 271.4 °C Boiling point: 1564 °C
A foil is a thin sheet of pure metal. Given its fragile nature, some foils have protective coatings.
