Question 49

Radioactivity and Nuclear Physics

One of the features of the fission process is that

  1. A.its products are not radioactive
  2. B.it leads to chain reaction
  3. C.neutrons are not released
  4. D.the sum of the masses of the reactants equals the sum of the masses of the products
Show the answer and explanation

Answer: B (it leads to chain reaction)

Explanation

Each fission releases extra neutrons that can split more nuclei, so fission can lead to a chain reaction. Its products are radioactive and some mass is turned into energy.
