Where was the first synthetic element, technetium, discovered?
Quick Answer
Technetium was first discovered in a laboratory rather than in nature. It was identified in 1937 by Carlo Perrier and Emilio Segrè from samples exposed to cyclotron bombardment in Berkeley, California.
The Full Story
Technetium was the first element to be produced artificially and then recognized as a new element. Carlo Perrier and Emilio Segrè identified it in 1937 using radioactive material produced by bombardment in a cyclotron at the University of California, Berkeley. Its discovery was historically important because it confirmed that artificial nuclear reactions could create new elements. Technetium has atomic number 43 and no stable isotopes. It is now used in medical imaging, especially technetium-99m, which is one of the most important diagnostic isotopes in nuclear medicine.
