A nucleus emits a radiation, neither its mass number nor charge number change in the radiation is:
Correct answer: B. γ
- A. α
- B. γ
- C. β
- D. Neutron
Explanation
In the context of nuclear physics, when a nucleus emits radiation without any change in its mass number (A) or charge number (Z), the radiation being emitted is typically a gamma (γ) ray.

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.
