Fission fragments usually decay by emitting:
Correct answer: B. electrons and neutrons
- A. α-particles
- B. electrons and neutrons
- C. Positron and neutrinos
- D. Only neutrons
Explanation
Nuclear fission is when heavy unstable nuclei disintegrate to two lighter nuclei along with the emission of a neutron, electron, and energy.

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
