YT2095 Posted December 27, 2007 Share Posted December 27, 2007 a Thought just occurred to me, if you have a Beryllium isotope that Alpha decays wouldn`t you get TWO lots of alpha from one decay? since 2 elements down from Be is He. Link to comment Share on other sites More sharing options...
insane_alien Posted December 27, 2007 Share Posted December 27, 2007 no, because beryllium 8 does not undergo alpha decay. an alpha particle has to have 2 neutrons and beryllium 8 would be the only one able to to eject 2 alphas without any excess neutrons and such.

Be-8 splits into two alphas in very short order. It's one of the rare even-even nuclei on/near the line of stability that's not stable, since alphas are so tightly bound. The other nearby unstable Be isotopes beta decay. Link to comment Share on other sites More sharing options...
