ANSWER:
The answer is given in the step by step
Explanation:
Fission is a reaction in which a heavy nucleus, when bombarded with neutrons, becomes unstable and decomposes into two nuclei, whose masses are of the same order of magnitude, and whose sum is slightly less than the mass of the heavy nucleus, which causes a great release of energy and the emission of two or three neutrons. In the fission, Uranium 235 is obtained (split apart) from a neutron and from this we obtain Uranium 236 and from here we can obtain Barium, Krypton, Plutonium, and other neutrons.
Fusion is a reaction in which two very light nuclei come together to form a heavier stable nucleus, with a mass slightly less than the sum of the masses of the initial nuclei. This mass defect results in a large release of energy. The energy produced by the Sun has this origin. A typical nuclear fusion reaction involves the combination of two isotopes of hydrogen, deuterium and tritium, to form a helium atom plus a neutron.
