By emitting a β. particle and a γ. particle simultaneously, the nucleus increases its charge by:
Correct answer: A. 1
- A. 1
- B. No change will be observed
- C. 2
- D. 4
Explanation
Gamma decay does not change the charge or mass number. Beta (β⁻) decay involves a neutron becoming a proton, which increases the atomic number (and thus the nuclear charge) by one. Therefore, the net change in charge is +1.

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.
