The history of Flerovium
| Discovery | Joint Institute for Nuclear Research, Lawrence Livermore National Laboratory (1998) |
| Named by | JINR, LLNL |
Discovery of flerovium Flerovium is named after the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research in Dubna, Russia, where the element was discovered in 1998. The lab's name, in turn, honours Russian physicist Georgy Flyorov (Флёров in Cyrillic, hence the transliteration of "yo" to "e"). IUPAC adopted the name on 30 May 2012. The name and symbol had previously been proposed for element 102 (nobelium), but was not accepted by IUPAC at that time. | |
