Correct answer: B. Increases

  • A. Decreases
  • B. Increases
  • C. Remains the same
  • D. None of the above

Explanation

Option B is correct because when a radioactive nucleus emits a beta particle, the proton-neutron ratio increases because the mass number is the same but the atomic number decreases by one.

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.
