← ScienceWhich consequence results when uneven nucleon distribution destabilizes the nucleus?
A)Alpha decay releases kinetic energy✓
B)Electron capture becomes energetically favorable
C)Binding energy per nucleon increases
D)Nuclear fusion reaction rate declines
💡 Explanation
Alpha decay occurs because unbalanced nucleon distribution weakens the strong nuclear force. This lowers the total binding energy and the Coulomb repulsion contributes enough energy, therefore the alpha particle is emitted rather than remaining bound, which would yield lower average binding.
