When was the element technetium first discovered?

Technetium was first identified in 1937 by Emilio Segrè and Carlo Perrier. It was the first element to be produced artificially and then confirmed as a new element, rather than being found naturally first. The name technetium comes from the Greek technetos, meaning “artificial,” reflecting its laboratory origin. It holds a special place in the periodic table because it has no stable isotopes.
