Chapter 43 - Energy from the Nucleus - Questions - Page 1330: 6

Answer

In fusion reaction, two or more light nuclei fuse into a heavier nucleus and energy is produced. The total mass of the nuclei participated in the reaction is not conserved before and after the reaction. Some mass of target nuclei is transformed into energy. Therefore, in a fusion reaction, the mass of the product is less than the sum of the masses of the projectile and target nuclei.
