a radioactive, metallic chemical element, one of the noble gases: a transactinide produced by bombarding plutonium with calcium ions: symbol, Fl; at. no. 114
Origin of fleroviumfrom the Flerov Laboratory of Nuclear Reactions in Russia, after G. Flerov (1913-90), Russian physicist
An artificially produced radioactive element with atomic number 114 that has only been produced in trace amounts and has five observed isotopes with mass numbers ranging from 285 to 289. Its most stable isotope has a half-life of about 2.7 seconds. See Periodic Table.
Origin of fleroviumAfter the Flerov Laboratory of Nuclear Reactions at the Joint Institute for Nuclear Research located in Dubna, Russia, which collaborated in its discovery
- The chemical element with atomic number 114 (symbol Fl).
Named after the Flerov Laboratory of Nuclear Reactions, with -ium.
