← ScienceWhich threshold failure follows decreased nuclear binding stability?
A)Spontaneous fission reaction initiation✓
B)Increased rate of alpha decay
C)Suppressed rate negative beta decay
D)Enhanced neutron capture cascade
💡 Explanation
Spontaneous fission results because insufficient binding energy means the nucleus’s total energy exceeds that of the fission fragments; surface tension is unable contain the disruptive Coloumb forces. Therefore, fission begins, rather than other decays which remain energetically unfavorable.
