WebAbstract. According to Burbidge, Burbidge, Fowler and Hoyle (B 2 FH), most of the elements were synthesized in the interior of stars by at least seven different types of nuclear processes. Deuterium, lithium, beryllium and boron are very unstable, however, at the temperatures of stellar interiors, so that they must have been produced in regions ... The first element to be synthesized, rather than discovered in nature, was technetium in 1937. This discovery filled a gap in the periodic table, and the fact that technetium has no stable isotopes explains its natural absence on Earth (and the gap). With the longest-lived isotope of technetium, Tc, having a 4.21-million-year half-life, no technetium remains from the formation of the Earth. Only minute traces of technetium occur naturally in Earth's crust—as a product of spontaneous fission of …
