Question:
Whether the total mass of nuclei increases, decreases or remains unchanged?
Whether the total mass of nuclei increases, decreases or remains unchanged?
Show Hint
In nuclear fusion, the total mass of the nuclei decreases, and the missing mass is converted into energy.

Solution and Explanation
The total mass of the nuclei decreases during a fusion reaction. This mass is converted into energy according to Einstein’s equation \( E = mc^2 \). The total energy released in the form of binding energy is greater than the energy required to overcome the mass defect.
