The transformation of a neutron into proton in the nucleus gives rise to emission of:
Correct answer: A. Beta particles
- A. Beta particles
- B. Gamma particles
- C. Alpha particles
- D. X-rays
Explanation
Option A is correct because the transformation of a neutron into a proton in the nucleus gives rise to the emission of a beta (β) particle. This process is known as beta decay. In beta decay, a neutron inside the nucleus undergoes a transformation where it is converted into a proton, emitting a beta particle in the process. The beta particle can be either a beta-minus (β-) particle, which is an electron (e⁻), or a beta-plus (β+) particle, which is a positron (e⁺).

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.
