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.
  
  • Osmium metal does not oxidize in air unless it is heated.
  • But if it heated den it forms Osmium Tetroxide, which is highly toxic.

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.
  
  • Its has very limited uses and its alloys are very hard and are used in the manufacturing of pen tips, pivots, needles and electrical contacts.
  • It is also used as industrial catalyst to speed up the chemical reaction.
