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.
- Samarium metals helps stimulating body metabolism.
- Samarium metals was 1st observed by Jean Charles Galissard de Marignac in Dydimia in 1853.

Uses & Benefits
- Plutonium was used in atomic bombs and still it is being used in various weapons and Ammunition industry.
-
It is also used in nuclear power plant as source of energy for space missions.
- Magnets of Samarium cobalt alloy are stronger than that of Iron and hence, they are used in microwave application.
- Samarium metal also used in optical lasers and infrared absorbing glasses and as a neutron absorber.
