difference between fusion and fission reactions

The nuclear reaction in which a heavy nucleus is broken into smaller nuclei, by releasing neutrons and energy, is called nuclear fission.The differences between nuclear fission and nuclear fusion can be drawn clearly on the following grounds: Key Differences Between Nuclear Fission and Nuclear Fusion The source of energy to all stars including Sun is the fusion of hydrogen nuclei into helium. higher degrees of temperature and high pascals of pressure. Moreover, extreme conditions are required for this process to take place, i.e. In this process, a substantial amount of energy is required to force low energy atoms to fuse. The mass of the nucleus formed is a bit lower than the aggregate of the masses of the individual nuclei. In nuclear fusion, two positively charged nuclei integrates to form a larger nucleus. Nuclear fusion implies a nuclear reaction, wherein two or more lighter nuclei fuse to create one heavy nucleus, which produces a tremendous amount of energy, such as hydrogen atoms fuse to form helium. These nuclei are radioactive, which continuously releases beta particles until each of them arrives at a stable end product. The nuclei formed during the reaction, are highly neutron-rich and unstable. The energy liberated during the nuclear fission can be utilised in the production of steam, which in turn can be used to generate electricity. In this process an enormous amount of energy is generated, as the mass of the nucleus (original), is slightly higher than the aggregate of the mass of its individual nuclei. Nuclear fission is a process, wherein the nucleus of the large atoms like uranium or plutonium, is bombarded with the neutron of low-energy, breaks into small and lighter nuclei.

Relatively high amount of energy is generated. Tremendous amount of energy is generated. Huge amount of energy is required to force nuclei to fuse. Requires less amount of energy to split nucleus. Nuclear fusion refers to a process in which two or more lighter atoms combine to create a heavy nucleus. Nuclear fission implies reaction in which a heavy nucleus is broken into smaller nuclei, by releasing neutrons and energy. Content: Nuclear Fission Vs Nuclear Fusion These two reactions are often understood together, which most people juxtapose, but the difference between nuclear fission and nuclear fusion lies in their occurrence, temperature, the energy required or produced. It liberates energy during nuclear fission and nuclear fusion reactions. Out of these energy sources, nuclear energy gives million times larger energy than the other sources. We get energy from various conventional and non-conventional sources, which include solar energy, wind energy, tidal energy, geothermal energy and nuclear energy. It comes in various forms and is capable of being converted from one form to another. It implies the strength and power that we require to perform the physical or mental activity.

With the rapid industrialisation, our demand for energy is increasing in the same ratio, because of the change in the way we live and do our work, as we are greatly dependent on machines to do our work, which consumes energy.
