Where was the first synthetic element created?

Technetium was the first element to be produced artificially, and it was created in 1937 at the University of California, Berkeley. Carlo Perrier and Emilio Segrè obtained it from a molybdenum target that had been exposed to bombardment in a cyclotron. Because technetium has no stable isotopes, it does not occur naturally in significant amounts on Earth. Its discovery was a major milestone in nuclear chemistry and expanded the periodic table beyond naturally occurring elements.
