Flerovium is an artificial element, and thus a standard atomic mass cannot be given. Like all artificial elements, it has no stable isotopes. The first synthesized isotope was 289Fl in around 1999. Flerovium has five confirmed isotopes, and possibly 2 nuclear isomers. The longest-lived isotope is 289Fl with a half-life of 2.6 seconds.
