← ScienceWhich consequence results when neutron number affects nuclear binding?
A)Increased probability of spontaneous fission✓
B)Enhanced alpha decay reaction kinetics
C)Reduced average atomic ionization energy
D)Stable isotope formation approaches certainty
💡 Explanation
Neutron excess reduces strong nuclear forces because unstable isotopes undergo spontaneous fission. The underlying mechanism is decreased binding energy per nucleon; therefore fission becomes more likely, rather than alpha decay or increased stability in ionization reactions.
