Interesting Facts
- Thulium metal can resist corrosion due to dry air .
- Only Tm-169 isotope of Thulium metal occur naturally.
- Beryllium is best anti corrosion metal.
- Beryllium is the lightest metal and still it is stronger than steel.
- It also finds various applications in Nuclear reactors as a reflector.
