In nucleus of uranium, the number of neutrons will be:
Correct answer: D. Different for different isotopes
- A. 92
- B. 143
- C. 235
- D. Different for different isotopes
Explanation
Atoms of an element having same number of protons but different number of neutron are called isotopes. This is the most accurate description. Uranium has several isotopes, and the number of neutrons can vary between them. The most common isotopes are uranium-235 and uranium-238, which have 143 and 146 neutrons, respectively.

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.
