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.
- Galena mineral contains almost 87% of Lead metal in it, Galena is sulfide mineral.
- The best available source of Lead metal today is by recycling automobile batteries.

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).
- It is also used in insecticides, hair dyes and as an anti-knocking additive for petrol. But all these are banned by the government as Lead metal is known for detrimental to health.
