Understanding Nuclear Stability: The Role of Binding Energy

[QUOTE="Mark Zhu, post: 6414880, member: 654141"] [B]Homework Statement:[/B] See Attachment [B]Relevant Equations:[/B] See Attachment This is an example from my textbook that I am having trouble understanding. So the binding energy of Beryllium-8 is positive 56.6 MeV, so it means the nuclide is stable, right? My textbook seems to use the reference of positive binding energy as being stable. And so that means alpha decay for Beryllium-8 is unfavorable, because that binding energy is negative. Then why does the textbook say, "From the standpoint of energy, there is no reason why a 8Be nucleus will not decay into two alpha particles" and that Beryllium-8 is unstable, yet it has a positive binding energy? Thank you. [/QUOTE]
