The number of neutrons in ₉₂ U ²³⁵ nucleus is

Options

  1. A327
  2. B235
  3. C143
  4. D92

Correct answer

C. 143

Step-by-step solution

The atomic mass or mass number of an atom _ Z X^ A is given by A=Z+N where, A= mass number, Z= atomic number and N= number of neutrons. For, ₉₂ U ²³⁵, A=235 and Z =92 N=A-Z=235-92=143
