![]() this process happens repeatedly after the first reaction. No neutron is required for nuclear fusion. A slow neutron is required for nuclear fission. In this process, two lighter nuclei combine into a larger nucleus. In this process, a heavy nucleus breaks into two smaller nuclei. Difference between nuclear fission and nuclear fusion in tabular form SL No. The Sun can supply such a huge amount of light energy only due to the nuclear fusion process inside it.Nuclear fusion is used to produce hydrogen bombs.In this process, hydrogen atoms combine to form helium atoms and release a huge amount of energy.Ĥ 1H 1 + heat = 2He 4 + 2 1e 0 + energy Uses of nuclear fusion The Sun can generate such an amount of energy by the nuclear fusion process on it. The source of all energy on Earth is the Sun. Therefore, to get nuclear energy from nuclear fusion, the nuclear fission process has to take place first. Now, the source of this huge energy is nuclear fission. We need high temperature or heat energy to combine even two lighter nuclei by nuclear fusion process.But the huge amount of required energy to combine two heavy nuclei is not possible to generate. Therefore, to combine these two light nuclei we need relatively smaller external energy. Because two lighter nuclei will exert smaller electrostatic repulsive force. Only the nuclei of light elements like hydrogen and hydrogen-like elements can be used in nuclear fusion.There are two main conditions for the nuclear fusion reaction. Nuclear fusion requires a huge amount of external energy to combine the nuclei. This is the opposite phenomenon of nuclear fission. Nuclear fusion is a nuclear phenomenon in which two or more smaller nuclei combine to form a new and heavy nucleus. It also has uses in nuclear reactors to produce electricity.Nuclear fission is the application to produce an atom bomb.The examples of nuclear fission are as followings – Nuclear fission has uses in producing atom bombs.This is why nuclear fission is known as a chain reaction. neutrons form in a chain way and these neutrons take part in further nuclear fission reactions. In this cumulative process 1, 3, 9, 27, 81,…. These three neutrons also take part in another three nuclear fission and produce 9 neutrons after breaking those heavy nuclei. During the first interaction of a neutron and the heavy nucleus, the nucleus breaks into two parts and also creates 3 new neutrons. One can perform several consecutive reactions by using only one neutron. This is why a slow neutron is used in nuclear fission. It cannot absorb the energy of a high-speed neutron because of less interaction time. This breaking up of a heavy nucleus occurs after absorbing the energy of that slow neutron. In nuclear fission, a neutron of low speed is required to collide with the heavy nucleus to break it into two parts.A heavy nucleus breaks into two nuclei of almost equal masses. ![]() Nuclear fission is a nuclear phenomenon in which a heavy nucleus breaks up into two nuclei of almost equal masses (usually in 5:7 ratio) after colliding with a slow neutron. Difference between nuclear fission and nuclear fusion What is nuclear fission?.In this article, we are going to discuss the definition, properties, examples, uses and differences between nuclear fission and nuclear fusion in tabular form. But these two phenomena occur in different conditions and the amount of heat generation is also different in these two phenomena. Nuclear fission and nuclear fusion are two nuclear phenomena to produce nuclear heat energy.
