Both Flerovium and Livermorium were detected in Russian labs over ten years ago (1998 and 2000), but the half-lives of the particles were so short that the scientists were unable to verify their discoveries. The discoveries were confirmed in 2004 through a collaborative effort scientists from the Joint Institute for Nuclear Research (JINR) in Dubna, Rusia, and the Lawrence Livermore National Laboratory (LLNL) in Livermore, California, USA, led by Rusian physicist Yuri Tsolakovich Oganessian (1933-) and American chemist Kenton J. (Ken) Moody. The Dubna-Livermore collaboration be credited with the discovery of the new element with Z = 114. Temporarily known as ununquadium, flerovium was named in honor of the Flerov Laboratory of Nuclear Reactions where superheavy elements are synthesised. The Soviet physicist Georgi Nikolaevich Flerov (1913-1990) was a pioneer in heavy-ion physics who founded the JINR in Dubna. It is a synthetic radioactive element that do not occour naturally in earth. Flerovium was produced by bombarding plutonium-242 with calcium-48.
