Physical Properties of Technetium

  • The metal is the lightest element that has all isotopes as radioactive and none are stable.
  • Commonly obtained in a powder form which will be in grey colour.
  • Artificially generated through many ways like fission, water disposal, and neutron activation.

Certain Facts About Technetium

  • As it is radioactive metal, it is toxic and harmful to life.
  • The compound of 99Tc is very contaminative in nature and hazardous for life.
  • One must use a safety glove box while handling the chemical.

Uses of Technetium

  • Used as a catalyst similar to the way rhenium and palladium are used.
  • Protects steel from corrosion.
  • Certain compounds are helpful in the manufacture of photoelectric nuclear batteries.
