Technetium is an artificial chemical element.
Technetium is a man made chemical element.
Technetium is a man made element; natural technetium exist only in ultra traces in uranium deposits.
Technetium was discovered in 1937 by Carlo Perrier and Emilio Segre. Technetium has the symbol Tc and the atomic number 43.
The first synthetic element made by a particle accelerator was technetium. Soviet scientists successfully synthesized technetium in 1937 using a cyclotron. Technetium is element 43 in the periodic table with the symbol Tc.
Technetium has no stable isotopes but at least 30 artificial ones have been identified.
This element is technetium (Tc); but today traces of natural technetium were discovered.
Technetium was discovered by Emilio Segre and Carlo Perrier in 1936 at the University of Palermo, Sicily, Italy.

Technetium is an artificial chemical element and is extracted from fission products, prepared by neutron activation or by irradiation in particles accelerators.
