Considering this, is promethium naturally occurring?Source: Promethium has not been found in any observable amounts in the earth’s crust. It is found in miniscule amounts in uranium ores as a product of uranium decay. Promethium can be produced as a product of uranium fission. Promethium has no naturally occurring isotopes.Subsequently, question is, what are man made or synthetic elements? A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor or particle accelerator, or explosion of an atomic bomb; thus, they are called “synthetic”, “artificial”, or “man-made”. Keeping this in consideration, is promethium man made? Promethium has no known biological role. Promethium’s longest-lived isotope has a half-life of only 18 years. For this reason it is not found naturally on Earth. It has been found that a star in the Andromeda galaxy is manufacturing promethium, but it is not known how.What is promethium found in? 1945
