Interesting Facts
- Gadolinium is not found free in nature, hence it is not a native metal.
- Gadolinium metal found in minerals like Monazite and Bastnaesite.
- 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
- Its alloys are also used in making Magnets, electronic components and Data storage devices.
- Compound of Gadolinium metal are used in magnetic resonance imaging (MRI).
- 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.
