If "A" is the atomic mass and "Z" is the atomic number of an atom, then the charge on its nucleus will be:
Correct answer: B. +(Z)e
- A. + (A - Z)e
- B. +(Z)e
- C. + Z - A.e
- D. +A.e
Explanation
Charge on nucleus = Z(+e)Neutrons are neutral thus charge is due to protons which equals to 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.
