Question 33

Radioactivity

Nuclear fission involves the splitting of a heavy element into two nuclei of

  1. A.nearly equal masses with a release of energy and radiation.
  2. B.equal masses with a release of energy
  3. C.equal masses with a release of energy and radiation.
  4. D.unequal masses without any release of energy.
Show the answer and explanation

Answer: A (nearly equal masses with a release of energy and radiation.)

Explanation

In fission a heavy nucleus such as U-235 splits into two lighter nuclei of roughly similar size, releasing a lot of energy, neutrons and radiation.
