History
In January 1999, Ununquadium was reported informally by scientists at Dubna (Joint Institute for Nuclear Research) in Russia. They apparently used isotopes that came from the Lawrence Livermore National Laboratory, USA. The same team produced another isoptope of Uuq three months later. Since then, no one has seriously challenged the finding.
