Atomic Physics

Step 1: Understand the meaning of BE/N.
BE/N means binding energy per nucleon. To find the total binding energy of a nucleus, we multiply the binding energy per nucleon by its mass number.
For the given nuclei:
Step 2: Find the total initial binding energy.
In the reaction, two nuclei of and one nucleus of combine to form one nucleus of .
So, the total initial binding energy is:
Step 3: Find the final binding energy.
The final nucleus formed is , whose total binding energy is:
Step 4: Calculate the energy produced.
Energy released in a nuclear reaction is equal to the increase in total binding energy.
Thus, the reaction releases of energy.
Final Answer: 14 MeV.
