The proton number of a nucleus increases after emission of:
Correct answer: A. Negative ß particle
- A. Negative ß particle
- B. Positive B particle
- C. Proton
- D. Alpha particle
- E. Neutron
Explanation
In beta-minus decay, a neutron is converted into a proton, and an electron (beta particle) is emitted. The atomic number increases by 1, changing the element to the next higher one, while the mass number remains the same.

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.
