History


Ununquadium was first made by research scientists at the Joint Institute for Nuclear Research in Dubna, Russia in 1998. Scientists bombarded a plutonium target with calciumions. Ununquadium (Uuq) is a temporary element name until it is given an official name by The International Union of Pure and Applied Chemistry (IUPAC). As a result of its position in the periodic table ununquadium might have been expected to be classed as one of the "other metals", with properties similar to lead. Too little of the element has been synthesized for its properties to be certain. With a [Rn] 5f14 6d10 7s2 7p2 configuration chemists wondered how the filled 7p1/2 subshell might influence the chemical properties of ununquadium. Significant spin-orbit splitting between the spherical 7p1/2 and distorted 7p3/2 orbitals meant estimates ranged from a noble gas-like behavior to a lead-like behavior. Initial results indicate ununquadium may exhibit noble gas-like behaviour
