One isotope of Uranium is U-238. Any other isotope of Uranium must have
Correct answer: B. 92 protons
- A. 146 protons
- B. 92 protons
- C. 92 neutrons
- D. 146 neutrons
Explanation
Isotopes are atoms of the same element with same number of protons but different number of neutrons. Every Uranium atom has 92 protons independent of which isotope it is or what its mass number is.

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.
