Interesting Facts
- Thulium metal can resist corrosion due to dry air .
- Only Tm-169 isotope of Thulium metal occur naturally.
- 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
- Thulium metal produces isotopes that emits X-rays. This isotope is used in X-ray machine.
-
Thulium element is also used in Surgical equipment like laser.
- 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.
