Facts
Interesting Facts
  • Bohrium metal is also known as Unnilseptium (Uns) and Nielsbohrium (Ns).
  
  • Bismuth metal is soluble and reacts with concentrated nitric acid.
  • It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.

Uses
Uses & Benefits
  • Currently known uses of Bohrium metal are limited to research purpose only.
  
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
