Isotope van flerovium
From Wikipedia, the free encyclopedia
Die chemiese element flerovium (Fl), met ’n atoommassa van ongeveer 289 u, het geen stabiele isotope nie en word dus as ’n radioaktiewe element geklassifiseer. Die vyf isotope is onstabiel en het ’n relatief kort halfleeftyd (die meeste minder as ’n sekonde).
In die natuur kom geen flerovium voor nie; alle isotope is sinteties in ’n laboratorium berei. Die eerste sintetiese isotoop was 289Fl, in 1996.
Die kortslewende isotoop van flerovium is 285Fl, met ’n halfleeftyd van ongeveer 125 millisekondes. Die langslewende een is 289Fl, met ’n halfleeftyd van 2,6 sekondes.
