← ScienceWhich consequence results when the binding energy per nucleon sharply decreases in very heavy nuclei?
A)Increased probability of spontaneous fission✓
B)Enhanced rate of nuclear fusion
C)Elevated neutron capture cross-section
D)Greater alpha particle stability
💡 Explanation
Decreasing binding energy signifies that the nucleus is less stable. Therefore, spontaneous fission occurs more readily, because the nucleons are held together less tightly due to diminished strong nuclear force, rather than favoring fusion or capture.
