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.
- Erbium metal is used as alloyed with Vanadium to make it softer.
- Recent studies shows that it is helpful for metabolism.

In 1880
In 1842
Abundance In Earth's Crust
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 has a tendency to get tarnished in the open air, but when alloyed with elements like erbium, vanadium, its hardness levels decreases.
- Its compounds like Erbium oxide is used in safety glasses of welders and metal workers.
