Interesting Facts
- Bohrium metal is also known as Unnilseptium (Uns) and Nielsbohrium (Ns).
- Samarium metals helps stimulating body metabolism.
- Samarium metals was 1st observed by Jean Charles Galissard de Marignac in Dydimia in 1853.

Uses & Benefits
- Currently known uses of Bohrium metal are limited to research purpose only.
- 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.
