History
On February 1, 2004, the synthesis of ununpentium and ununtrium were reported in Physical Review C by a team composed of Russian scientists at Dubna University's [1] Joint Institute for Nuclear Research [1], and American scientists at the Lawrence Livermore National Laboratory . Their discovery of the element still awaits confirmation. [1]
The team reported that they bombarded americium (element 95) with calcium (element 20) to produce four atoms of ununpentium (element 115). These atoms, they report, decayed to ununtrium (element 113) in a fraction of a second. The ununtrium produced then existed for 1.2 seconds before decaying into known elements.
Ununpentium is a temporary IUPAC systematic element name.
Ununpentium in popular culture
Ununpentium was theorized to be inside the island of stability. This probably explains why it was mentioned regularly in popular culture before it was actually created:
- In the world of UFO conspiracy theory culture during the 1980s and 1990s, Bob Lazar asserted that ununpentium functioned as "fuel" for UFOss, being "stepped up" to ununhexium under "particulate bombardment," and that the ununhexium's decay products would include antimatter. These processes are considered implausible in terms of nuclear physics, not least due to the very short half-lives of both elements.
- As a reference to this kind of UFO conspiracy theory, in the X-COM game series there is an element called elerium-115 or just elerium ("elerium-115" probably being an error as in this form the number would have referred to the number of nucleons instead of the atomic number, meaning that elerium would have no neutrons, which is not possible).
- A fictional stable isotope of ununpentium occurs in the game Dark Reign.
- A fictional stable isotope of ununpentium occurs in the movie The Core.
