← ScienceWhich outcome results when enriched Uranium-235 undergoes neutron capture?
A)Nuclear fission chain reaction initiates✓
B)Alpha decay produces Thorium-231
C)Beta decay generates Neptunium-239
D)Isotopic enrichment becomes less efficient
💡 Explanation
Nuclear fission initiates because neutron capture by Uranium-235 causes nuclear instability and subsequent splitting, releasing more neutrons, therefore sustaining fission, rather than alpha or beta decay which require different nuclear configurations.
