Uses & Benefits
- Currently known uses of Ununseptium 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.
