![]() One class of nuclear weapon is the hydrogen bomb, which uses a fission reaction to "trigger" a fusion reaction. One class of nuclear weapon is a fission bomb, also known as an atomic bomb or atom bomb. energy needs, making it one of the top five energy generation sources in the country. The energy released by fusion is three to four times greater than the energy released by fission. Nuclear energy accounts for about 20 of U.S. The energy released by fission is a million times greater than that released in chemical reactions but lower than the energy released by nuclear fusion. Fission and fusion are two ways to release energy from atomic nuclei via nuclear reaction. The fusion reaction process happens in stars, such as the sun, among others. In terms of spelling there is only a different vowel and a consonant between them, but in reality these are two exactly opposite reactions in the atom. In nature, fission reactions are unusual. Fission and fusion reactions both release energy. Fission typically involves large nuclei whereas fusion involves smaller nuclei. ![]() Fission and fusion are both nuclear processes that involve the interactions of atomic nuclei. Fusion is the transformation of smaller atoms or molecules into bigger ones. Fission is the splitting of nuclei and fusion is the merging of nuclei. Takes little energy to split two atoms in a fission reaction.Įxtremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion. A big atom or molecule gets divided into two or smaller ones during fission. Both fission and fusion can be used as an energy source, but fission is the only one that’s used in modern nuclear power plants. Fusion Nuclear fusion is the process of fusing multiple atoms together, while nuclear fission is the process of breaking them apart. High density, high temperature environment is required. What Is the Difference Between Fission vs. The best example of fusion is the sun, where two lighter nuclei get together to form a heavier nucleus. The main difference is that fission is the splitting of a heavy, unstable nucleus into two smaller nuclei, while fusion reactions involve combining two light. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.įission is the splitting of a large atom into two or more smaller ones.įusion is the fusing of two or more lighter atoms into a larger one.įission reaction does not normally occur in nature.įission produces many highly radioactive particles.įew radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that.Ĭritical mass of the substance and high-speed neutrons are required. The basic difference between fusion and fission lies in the understanding of what happens to the atoms in each reaction. Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-powered atomic bonds between the particles within the nucleus. ![]()
