3 Uses
3.1 Uses & Benefits
  • Currently known uses of Copernicium metal are limited to research purpose only.
  • 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.
