First artificially produced chemical element
Webtechnetium (Tc), chemical element, synthetic radioactive metal of Group 7 (VIIb) of the periodic table, the first element to be artificially produced. The isotope technetium-97 (4,210,000-year half-life) was discovered (1937) … Nuclear transmutation is the conversion of one chemical element or an isotope into another chemical element. Nuclear transmutation occurs in any process where the number of protons or neutrons in the nucleus of an atom is changed. A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay, where no outside caus…

A synthetic element is one of 24 known chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made". … See more All elements with atomic number greater than 94 decay quickly enough into lighter elements such that any atoms of these that may have existed when the Earth formed (about 4.6 billion years ago) have long since decayed. … See more Technetium The first element to be synthesized, rather than discovered in nature, was technetium in 1937.
