← ScienceWhich outcome results if the mass defect decreases disproportionately within a heavy nucleus?
A)Lowered binding energy per nucleon✓
B)Increased probability of beta decay
C)Enhanced alpha particle emission rate
D)Greater neutron absorption cross-section
💡 Explanation
Lowered binding energy occurs because mass defect directly correlates to the energy released upon nucleus formation, via mass-energy equivalence. Therefore, reduced mass defect translates to weaker nuclear forces, rather than enhanced decay processes under alternative conditions.
