Facts
Interesting Facts
  • It is found in copper ores and from the crust of the earth.
  • It is the most malleable and ductile metal.
  • Gold alloys are used in Dentistry as fillings, crowning, clips, etc. It is also used as an artificial limb joints.
  
  • Plutonium metal if obtain from ores of uranium metal.
  • Plutonium metal is very sensitive to the change in atmospheric conditions like temperature and pressure.
