The Full Story
Technetium is widely recognized as the first man-made element, first identified in 1937 by Carlo Perrier and Emilio Segrè. It was produced in a laboratory from molybdenum samples that had been irradiated. Technetium has no stable isotopes, which is why it does not exist in large natural deposits on Earth. Its discovery was a milestone in nuclear chemistry and artificial element production.
