← ScienceWhich outcome occurs when an isotope's neutron fraction increases?
A)Increased probability of spontaneous fission✓
B)Reduced material tensile strength forms
C)Decreased half-life of alpha decay
D)Enhanced oxidation reaction with fluorine
💡 Explanation
An increased neutron fraction in an actinide isotope leads to increased probability of spontaneous nuclear fission because this alters the energetics of the nucleus via increased Coulomb repulsion. Therefore, spontaneous fission becomes more likely, rather than other decay modes like alpha emission.
