Interesting Facts
- Einsteinium is the transuranic element found in US.
- Only 0.01 mg of Einsteinium was synthesized in 1961.
- 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.

Uses & Benefits
- Currently known uses of Einsteinium 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.
