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.
- Tungsten element has the second highest melting point.
- Pure tungsten can easily cut down with the help of hacksaw.

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.
- Tungsten and its alloys are used in high-temperature applications like welding electrodes, high-temperature furnace, etc.
- Tungsten carbide is very hard and used in metal working, mining and petroleum industry.
