Technetium: meaning, definitions and examples

The name technetium is derived from the Greek word 'technetos', meaning 'artificial', reflecting its status as the first artificially produced element. It was discovered in 1937 by Italian scientists Carlo Perrier and Emilio Segrè, who isolated it from a sample of uranium. The element's existence was predicted in the periodic table by Dmitri Mendeleev, but it was not until nearly three decades later that it was actually obtained in a laboratory setting. Technetium's most stable isotope, technetium-98, has a half-life of about 4.2 million years, and it was initially found in trace amounts within uranium ores. Its discovery contributed to the understanding of nuclear fission and the behavior of radioactive elements.
