← ScienceWhich outcome dominates when iron-56 undergoes nuclear fission?
A)Input energy exceeds binding energy✓
B)Chain reaction criticality escalates rapidly
C)Radioactive daughter products form promptly
D)Neutron emission induces further reactions
💡 Explanation
Energy input to split the stable nucleus surpasses its strong nuclear force, because iron-56 has the highest nuclear binding energy per nucleon. Therefore, fission is highly endothermic, rather than self-sustaining like uranium or plutonium fission which releases net energy.
