Interesting Facts
- Fermium metal is highly radioactive in nature.
- Fermium is synthetically produced metal.
- Osmium metal does not oxidize in air unless it is heated.
- But if it heated den it forms Osmium Tetroxide, which is highly toxic.

Uses & Benefits
- Currently known uses of Fermium metal are limited to research purpose only.
- Its has very limited uses and its alloys are very hard and are used in the manufacturing of pen tips, pivots, needles and electrical contacts.
-
It is also used as industrial catalyst to speed up the chemical reaction.
