The Discovery and Search for Trans-Uranium Elements

TLDR Trans-uranium elements, which are highly unstable and don't exist naturally, were discovered in the 1940s and 1950s through experiments involving nuclear fission and radiation. Researchers are now searching for an isotope of a heavy element that would be relatively stable or have a very long half-life, known as the "island of stability," which could revolutionize our understanding of the atom and material science.

Timestamped Summary

00:00 Trans-uranium elements are highly unstable, don't exist naturally, and are only created by humans.
02:43 Trans-uranium elements are highly unstable, have no practical use, and don't exist naturally, with uranium being the heaviest naturally occurring element.
05:02 In the 1940s and 1950s, Glenn Seaborg and his team at the University of California, Berkeley, discovered several trans-uranium elements through experiments involving nuclear fission and exposing heavy elements to radiation.
07:29 In the 1950s and 1960s, researchers at Berkeley and other institutions discovered several trans-uranium elements through various methods, including analyzing radioactive debris from hydrogen bomb tests and bombarding heavy elements with different types of radiation.
09:52 Researchers at various institutions, including Berkeley and the GSI Helmholtz Center for Heavy Ion Research, created several trans-uranium elements through the technique of bombarding atoms with other atoms, resulting in elements with short half-lives and high radioactivity, with each element being named after a significant person, place, or institution.
12:14 Researchers are searching for an isotope of a heavy element that would be relatively stable or have a very long half-life, known as the "island of stability," as most trans-uranium elements have short half-lives and are highly unstable.
14:29 Researchers in Dubna, Russia are working on creating elements 119 and 120 in the hopes of finding the "island of stability," which could revolutionize our understanding of the atom and material science.
