← ScienceWhich outcome increases vulnerability when nuclear binding falls sharply?
A)Increased susceptibility to neutron capture
B)Enhanced alpha decay probability
C)Spontaneous fission reaction✓
D)Decreation in electron shell stability
💡 Explanation
Reduced _nuclear binding energy_ causes a nucleus to be less stable; therefore spontaneous fission is more likely, because there's lowered resistance to separation into smaller fragments, rather than stronger binding favoring fusion of isotopes.
