Facts
Interesting Facts
  • Plutonium metal if obtain from ores of uranium metal.
  • Plutonium metal is very sensitive to the change in atmospheric conditions like temperature and pressure.
  
  • Manganese is an essential trace element in all forms of life.
  • Manganese metal oxidizes very easily, but it does not fuse that easily.

Uses
Uses & Benefits
  • Plutonium was used in atomic bombs and still it is being used in various weapons and Ammunition industry.
  • It is also used in nuclear power plant as source of energy for space missions.
  
  • This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
  • Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
