That is only theoretical half lives in most of the cases. The only
reference I have seen to it is atom number 114 with a half life of 2.6 s
and hints of an isomer of 114 with a half life of 60 seconds. Total
number of atoms 114 observed so far is only 80.
They are called stable but that is only in a relative sense.

Hi Goran and List,
What about the isotopes that reside within the "island of stability"?
Have any traces of them ever been detected? Those isotopes have
longer half-lives.
Best regards,

All the transuranium elements are highly unstable so any trace amounts
of the super heavy elements are gone in just seconds to days. I think it
is a safe bet that there are none ever detected in meteorites.
Plutonium (Pu 94) and neptunium (Np 93) are the only transuranium
elements that have half life measured in years and they are formed by
decay of uranium, but I've never heard about them being detected in
meteorites.

Hi List!
Does anyone know if super-heavy elements are found in meteorites (even
in tiny amounts)?
Specifically, elements 112 to 119 or the transitionary metals between
104 and 111?
Best regards,
MikeG
