Answer:
That is correct. Atomic fission is the process of splitting the nucleus of an atom into two or more smaller nuclei using a neutron. This process releases a large amount of energy in the form of heat and radiation. On the other hand, atomic fusion is the process of combining two or more atomic nuclei into a larger, more massive nucleus. This process also releases a large amount of energy. Both processes involve a conversion of mass into energy, according to Einstein's famous equation E=mc². This means that a small amount of matter can be converted into a large amount of energy. The reverse process, where energy is converted back into mass, is also possible and is observed in nature, for example in the formation of particles and antiparticles
