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.
  
  • Ytterbium metal is used in memory devices and tuneable laser.
  • It is also used as industrial catalyst as the other catalysts are too toxic and polluting.
