Technetium Technetium Symbol Tc Technetium Atomic Number 43 Technetium Atomic Mass 97 g.mol-1 Discovered by Carlo Perrier and Emilio Segre It is the lightest element and has a common oxidation state of 7. It has three isotopes which are radioactive and unstable. The isotopes and their atomic mass is as follows: 97Tc = 96.906 98Tc = 97.907 99Tc = 98.906 Table of Contents What is Technetium? Chemical Properties of Technetium Physical Properties of Technetium Certain Facts About Technetium Uses of Technetium Frequently asked questions 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.

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. The metal could be used to map the circulatory system and any disorders. Proposedly could be used in the optoelectric nuclear batteries.
