Bismuth was discovered by Geoffroy in 1540 and is named 'Bismuth' German word "wissmuth" meaning "white mass".

Some common usages for Bismuth: pharmaceuticals, fuses.

Definitions and Notes

Density listed is at a temperature of 20°C.

Isotopes are forms of an element who have the same atomic number but different mass because they contain different number of neutrons.

Half-life is the time required for a quantity of a subject to fall to half of its current quantity.
