Ununpentium

Ununpentium (eka-bismuth) is the temporary name of an 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. It is expected to be a hard low melting metal 250 degrees Celsius possibly slightly colored.

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 Joint Institute for Nuclear Research American scientists at the Lawrence Livermore National Laboratory.

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.

The synthesizing of the element also reported by scientists of Japan.

In May 2006 in the Joint Institute for Nuclear Research the synthesys of this element was confirmed by another method (the chemical identifying on final products of decay of element).

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, especially in UFO conspiracy theories, before it was actually created.
