Ununquadium (symbol: Uuq) is a chemical element in group 14 of the periodic table. It has attracted interest because of the possibility that 298Uuq might be at the centre of a (relative) "island of stability" among superheavy nuclides[1] and because the chemical properties of ununquadium might resemble those of the noble gases rather than other group 14 elements.[2]
The preparation of ununquadium was claimed in 1999 by the team of Oganessian et al. at Dubna in Russia:[3] these claims, and later results by the same team,[4][5][6] are under consideration by the IUPAC/IUPAP Joint Working Party on Discovery of Elements (JWP).[7][8]
