Ununbium (eka-mercury) is a chemical element in the periodic table that has symbol Uub and has the atomic number 112. Element 112 is one of the superheavy elements; its longest-lived isotope has a mass of 285 and a half-life of 11 min. Some research has referred to it as "eka-mercury". Following periodic trends, it is expected to be a liquid metal more volatile than mercury.
It was first created on February 9, 1996 at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany. This element was created by fusing a zinc atom with a lead atom by accelerating zinc nuclei into a lead target in a heavy ion accelerator.
