SUMMARY
Atoms with high atomic mass are inherently unstable and emit alpha, beta, or gamma rays to achieve stability. When an atom emits alpha rays, the binding energy of the emitted alpha particle is approximately 27 MeV. This emission increases the binding energy per nucleon of the parent atom due to the removal of two protons, which reduces the repulsive forces within the nucleus, thereby enhancing its stability. The underlying principles are rooted in nuclear structure and binding energy calculations.
