(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.
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.
