The difference between U235 and U238 atom is that
Correct answer: D. U238 contains 3 more neutron
- A. U238 contains 3 more protons
- B. U238 contains 3 more protons and 3 more electrons
- C. U238 contains 3 more neutrons and 3 more electrons
- D. U238 contains 3 more neutron
Explanation
Isotopes are the atoms of an element having same atomic number Z but difference mass number A. Thus, U238 contains 3 more neutrons.

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.
