Flerovium was synthesised in Dubna, Russia in 1998. As a synthetic element it is only possible to create in laboratory conditions. The work was a collaboration between the Joint Institute for Nuclear Research in Dubna and the Lawrence Livermore National Laboratory led by Yuri Oganessian and Ken Moody. Flerovium was synthesised by combining calcium 48 and plutonium 244. After 6 months of experiments one atom of Flerovium was created for two seconds.
