Interesting Facts
- Chromium is highly reactive, hence it is not found free in nature.
- Ores of Chromites mineral are the major source of Chromium metal.
- Almost 90% leather tanning is done with the help of chromium.
- Mendelevium metal is synthetically produced metal.
- Mendelevium metal has been produced in only trace amount.
