History
Ununquadium (Uuq) was the temporary IUPAC systematic element name. In 1998, a team led by Yuri Oganessian and Vladimir Utyonkov at the Joint Institute for Nuclear Research, Dubna produced flerovium by bombarding plutonium with calcium. In an experiment lasting 40 days, 5 x 1018 atoms of calcium to be fired at plutonium to produce a single atom of flerovium. Named after the founder of the Flerov Laboratory of Nuclear Reactions, the Soviet physicist Georgy Flyorov
