He x2?

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.

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.
