Period: 7
Standard state (20 oC): gas

Discovery: 2002 Yuri Oganessian & JINR Dubna (RU) & LLNL Livermore (US)
In 2002, the collaboration of the Joint Institute for Nuclear Research in Dubna (Russia) and the Lawrence Livermore National Laboratory (California, USA) produced oganesson by bombardment of a californium-249 target by the calicium-48 beam. The element is named after the Russian nuclear physicist Yuri Oganessian (1933-) for his pioneering contributions to transactinoid elements research.
