Facts

Interesting Facts
  • Thorium metal is used as an alternate option over Uranium for nuclear fuel.
  • Thorium metals appearance (silvery white, soft) is somewhat similar to Lead metal.
  
  • Beryllium is best anti corrosion metal.
  • Beryllium is the lightest metal and still it is stronger than steel.
  • It also finds various applications in Nuclear reactors as a reflector.
