Interesting Facts
- Plutonium metal if obtain from ores of uranium metal.
- Plutonium metal is very sensitive to the change in atmospheric conditions like temperature and pressure.
- Gadolinium is not found free in nature, hence it is not a native metal.
- Gadolinium metal found in minerals like Monazite and Bastnaesite.
