Which of the following is different for isotopes?
Correct answer: A. Neutrons
- A. Neutrons
- B. Protons
- C. Electrons
- D. All of these options are correct
Explanation
All isotopes have the same number of protons and the same number of electrons. The difference in the ratio between the number of protons (the number of protons stays the same) and the number of neutrons creates a difference in the nuclear reactions of the isotopes.

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.
