Ununquadium (eka-lead) is the temporary name of a radioactive Chemical element in the Periodic table that has the temporary symbol Uuq and has the Atomic number 114.
History
In January 1999, ununquadium was reported informally by scientists at Dubna (Joint Institute for Nuclear Research) in Russia. The same team produced another isotope of Uuq three months later. Since then, no one has seriously challenged the finding.Ununquadium is a temporary IUPAC Systematic element name. Some have termed it 'eka-lead', as its properties are conjectured to be similar to those of Lead.
Stable Ununquadium
Ununquadium does not occur naturally on the earth - it is entirely synthesized in laboratories. Its supposed Half-life is 30 seconds. An isotope of Ununquadium (Uuq-298) is thought to lie in the Island of stability, although this isotope has never been synthesized.See also
