Ununquadium is the temporary name of a chemical element in the periodic table that has the temporary symbol Uuq and has the atomic number 114.


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. Their discovery of the element still waits confirmation.


Ununquadium does not occur naturally, but if enough was created and put in one place it would create a radiation hazard.
