Facts about bismuth

Here are a few interesting facts about the bismuth element.

  1. Bismuth was given its name from the old German word “weissmuth”, meaning white substance.
  2. The bismuth element is present in the earth’s crust in the concentration of 9 parts per billion by weight.
  3. Around 9000 tons of bismuth is produced in the world annually.
  4. Bismuth expands on freezing. (This property is also seen in gallium, silicon, germanium and antimony).
  5. Bismuth sulfide is the ore of bismuth from which the majority of bismuth metal is extracted.

Properties of bismuth

Here is a list of some physical properties and chemical properties of bismuth.

Physical properties of bismuth

  • Bismuth has a silvery-brown appearance.
  • Bismuth is diamagnetic in nature.
  • Bismuth is a poor conductor of electricity and heat.
  • The melting point of bismuth is 544.7 K and its boiling point is 1837 K respectively.
  • There are many isotopes of bismuth and out of those isotopes, the most abundant isotope is 209Bi.
