Isotopes
Livermorium is an artificial element, and thus a standard atomic mass cannot be given. Like all artificial elements, it has no stable isotopes. The first isotope to be synthesized was 293Lv in 2000. There are four known radioisotopes from 290Lv to 293Lv. The longest-lived isotope is 293Lv with a half-life of 53 ms.
