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.
- Ruthenium element has been extracted from used nuclear fuel.
- Ruthenium metal also produces as a by-product of the Nickel mining.

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.
- It is used for producing chip resistors and contact.
- Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. It also works as catalysts for ammonia and acetic acid reaction.
