 Livermorium is expected to be near an island of stability centered on copernicium ( element 112 ) and flerovium ( element 114 ) . The reasons for the presence of this island are still not well understood . Due to the expected high fission barriers , any nucleus within this island of stability exclusively decays by alpha decay and perhaps some electron capture and beta decay . While the known isotopes of livermorium do not actually have enough neutrons to be on the island of stability , they can be seen to approach the island as in general , the heavier isotopes are the longer @-@ lived ones .
