Compared with the mass of a uranium nucleus before splitting, the split fragments have
A)less mass.
B)the same mass.
C)more mass.

Question

Quizplus · Accepted Answer

During the process of nuclear fission, the nucleus of uranium splits into two smaller nuclei, called fission fragments. This process releases energy and some particles. According to the law of conservation of mass and energy, the total mass of the fission fragments and the energy released during the fission process should be equal to the original mass of the uranium nucleus. However, due to the conversion of a small amount of mass into energy, the fission fragments have slightly less mass than the original uranium nucleus.
