Facts about bismuth
Here are a few interesting facts about the bismuth element.
- Bismuth was given its name from the old German word “weissmuth”, meaning white substance.
- The bismuth element is present in the earth’s crust in the concentration of 9 parts per billion by weight.
- Around 9000 tons of bismuth is produced in the world annually.
