Facts
Interesting Facts
  • Naturally occurring minor elements include Cadmium.
  • Cadmium is released into atmosphere to control volcanic eruption and forest fires.
  • It is used for electroplating of Steel for corrosion resistance.
  • It can absorb neutrons and used in nuclear reactor to control atomic fission.
  
  • Hassium metals rate of decay is very high.
  • Hassium metals 1st sample was synthesized through a nuclear reaction.

Uses
Uses & Benefits
  • It has very limited uses as it is a toxic metal and it can cause birth defects, cancer, etc.
  • Almost 80% of Cadmium metal is used in Nickel cadmium Batteries and now it is getting replaced with nickel hydride.
  
  • Currently known uses of Hassium metal are limited to research purpose only.
