Chemical Elements

Periodic Table

Definition of the Technetium Element
A radioactive metal, the first synthetically produced element, used as a tracer and to inhibit corrosion in steel.

Origin / Meaning of the name Technetium
The name originates from the Greek word 'technetos' meaning artificial

Classification of the Technetium Element
Technetium is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. An Element classified as a Transition Metals is ductile, malleable, and able to conduct electricity and heat.

Facts about the History and the Discovery of the Technetium Element
Technetium was discovered by Emilio Segre and Carlo Perrier in 1937 in Italy. Technetium was the first element to be artificially produced.

Occurrence the Technetium Element
Man-made but some red giant stars contain an emission line in their spectrum corresponding to the presence of technetium.

Associated Uses of Technetium
Rust preventative
Radioactive tracing in medicine

Technetium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Technetium is just one element that can be found.
