Ununpentium (eka-bismuth) is the temporary name of an unconfirmed synthetic superheavy element in the periodic table that has the temporary symbol Uup and has the atomic number 115. It is made by a fusion of Calcium and Americium. It has also been known as eka-bismuth.

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 [2], and American scientists at the Lawrence Livermore National Laboratory. Their discovery of the element still awaits confirmation. [3]

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 natural elements.

Ununpentium is a temporary IUPAC systematic element name.

In popular culture

Ununpentium has been theorized to be inside the island of stability. This probably explains why it was mentioned regularly in popular culture before it was actually created.
