Isotopes of flerovium - Wikipedia
Flerovium (114Fl) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized was Fl in 1999 (or possibly 1998). Flerovium has six known isotopes, along with the unconfirmed Fl, and possibly two nuclear isomers. The longest-lived isotope is Fl with a half-life of 1.9 seconds, but Fl may have a longer half-life of 19 seconds.
