What is Technetium?
- Technetium (Tc) is a chemical element in the periodic table with atomic number 43.
- It is a silvery-grey radioactive metal which looks similar to platinum.
- The metals name is derived from the Greek word Tekhnetos which means artificial.
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.
- The metal could be used to map the circulatory system and any disorders.
- Proposedly could be used in the optoelectric nuclear batteries.
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.
