Flerovium is radioactive and has the symbol Fl and the atomic number 114. The element is named after Russian physicist Georgy Flyorov, who founded the Joint Institute for Nuclear Research in Dubna, Russia, where the element was first discovered in 1999.
Element 114 has a 30-second half-life, which is much longer than element 112's. This is evidence of the "island of stability" that was predicted to occur around element 114 (where the combination of protons and neutrons would combine to make a stable structure).
A beam containing 48Ca was aimed into a244Pu target to make this atom.
The name Flerovium was adopted by IUPAC on May 31, 2012.
