Coined/History
Technetium’s existence was predicted by Dmitri
Mendeleev on the basis of periodic table before the element was discovered. The
element discovered by Emilio Segre and Carlo Perrier in Italy, in 1937 and was the first element
to be produced artificially. It was found in a sample of molybdenum, which was
bombarded by deuterons in the Berkeley cyclotron. All almost technetium isotopes
are radioactive such as technetium-99m with a short half-life and that it
binds chemically to biologically active molecules.
Definition
Technetium is a chemical element with atomic number 43
and atomic mass 98. It is found in trace amounts in nature and its main
production is made synthetically.
