  3. C-particle
  4. D-particle

Correct answer

B. 2 neutrons

Step-by-step solution

₉₂ U ²³⁵+ ₀ n^1 ₅₄ Xe ¹³⁹+ ₃₈ Sr ⁹⁴+2₀ n^1 Related Theory Moderators are used to slow down the neutrons produced from fission. This is necessary because many nuclear fuels (uranium-235, for instance) require neutrons to be slow-moving in order to absorb them. Nuclei with low mass numbers are most effective at doing so, therefore materials like water or graphite are often used. Caution In a nuclear fission, a heavy nucleus disintegrates into lighter nuclei. Large amount of energy is released during nuclear fission.
