  It's Elemental - The Element Ununbium
Ununbium was first produced by Peter Armbruster, Gottfried Münzenber and their team working at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany on February 9, 1996.
Ununbium's most stable isotope, ununbium-285, has a half-life of about 10 minutes.
Since only a few atoms of ununbium have ever been produced, it currently has no uses outside of basic scientific research.

  Ununbium (Uub)   (Site not responding. Last check: )
Ununbium is a synthetic, metallic element not found anywhere in our environment.
It was first discovered on February 9th, 1996 in Darmstadt, Germany at the GSI by Peter Armbruster, Gottfried Munzenberg and their coworkers, and was created by fusing a zinc atom with a lead atom.
The name ununbium will not be the elements official name; it is a temporary systematic name given to it by the IUPAC.

In a two-week experiment, one of the resultant atoms was unambiguously identified as an isotope of element 112 with mass number 277 and a half-life of 280 microseconds.
No name has yet been adopted for element 112, which is therefore called ununbium, from the Latin roots un for one and bi for two, under a convention for neutral temporary names proposed by the International Union of Pure and Applied Chemistry (IUPAC) in 1980.

Atomic number 112, also known as Ununbium is presumed to be a liquid at 298 K. The color is unknown, but is thought to be either a metallic silvery white or gray color.
It is now the heaviest atom ever produced by man. Ununbium reacts with a lot of different compounds such as air, water, halogens, acids, and bases.
Ununbium was discovered on February 9th, 1996 at the Gesellschaft fur Schwerionenforschung in Darmstadt, Germany by a group of scientist.

After that, the scientists searched for signs of ununbium decay and compared their detector positions with those of the two other elements.
Although ununbium is not yet recognized as an official element, the researchers said they have achieved their goal of confirming reports that the bombardment process produced element 112 and that getting a bead on its chemistry was a bonus.

 Periodic Table of the Elements - National Research Council Canada
Ununbium is a synthetic element (number 112) produced from the fusion of lead and zinc.
It took German scientists several weeks to produce one atom of this element by bombarding billions and billions of zinc atoms at a lead target.
Few atoms of ununbium have been synthesized as this element decays after a fraction of a thousandth of a second, emitting alpha particles – fast-moving helium-like particles – to produce element 110.
