When a radioactive nuclide decays consecutively by emitting an α-particle, a β-particle and γ-ray the change in the nucleon number and atomic number are:
Correct answer: D. D option
- A. A option
- B. B option
- C. C option
- D. D option
Explanation
Equation can be written as:AZX → A-4Z-1Y + 42He + 0-1eThus, there is visible decrease in nucleon number as well as proton number.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
