Isotopes of meitnerium
Meitnerium (Mt) is a synthetic element, and thus a standard atomic mass cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized was 266Mt in 1982 (this is also the only isotope directly synthesized, all other isotopes are decay products of heavier elements). There are eight known isotopes, from 266Mt to 278Mt. There may also be two isomers. The longest-lived of the known isotopes is 278Mt with a half-life of 8 seconds.
