![]() ![]() If an uncontrolled chain reaction occurs, a huge amount of energy may be released in an explosion. Fusion is the fusing of two or more lighter atoms into. Control rods, which absorb neutrons, are lowered into the nuclear reactor to slow down the chain reaction and then lifted out of the reactor to speed up the chain reaction. Fission is the splitting of a large atom into two or more smaller ones. ![]() And although it is true that huge amounts of energy can be released, considerable effort is needed to do so in practice. Given that it requires great energy separate two nucleons, it may come as a surprise to learn that splitting a nucleus can release vast potential energy. In nuclear power stations, the amount of energy produced is controlled by controlling how fast the chain reaction can occur. Both fission and fusion are nuclear reactions that produce energy, but the processes are very different. In simplest terms, nuclear fission is the splitting of an atomic bond. In a nuclear power station, these gamma rays can be used to heat water, producing steam to turn turbines and generate electricity. This is called a chain reaction.Įnergy that is not transferred to the smaller nuclei or the neutrons is released as gamma rays. Nuclear fission and nuclear fusion both are nuclear phenomena that release large amounts of energy, but they are different processes which yield different products. If any of these neutrons are moving slow enough to be absorbed by another atom, they may cause that nucleus to undergo fission as well. Two or three neutronsare also produced when fission occurs. All of the fission products have kinetic energy. Fusion, on the other hand, occurs when two or more light-weighted atoms fuse together. The new nuclei are also unlikely to be the same size as one another. In fission, an atom splits into two or more tiny, lighter atoms. Nuclear fission occurs when the nucleus of an atom is split into two smaller nuclei, releasing a significant amount of energy. Q2 What is nuclear fusion It is the process in which two or more light nuclei collide with each other to form a heavier nucleus. These will be of a different elementsthan the original nucleus. After all, if energy is released when a nucleus is split, how can it also be released when nucleons are combined together The difference between fission and. Nuclear fission and nuclear fusion are processes involving the release or absorption of energy in atomic nuclei. Q1 What is nuclear fission It is the process in which the nucleus of an atom splits into lighter nuclei through a nuclear reaction. When the nucleus splits, two smaller nuclei are produced. This makes the nucleus unstable and forces fission to occur. In order to force a nucleus to split up, we can make it absorb a neutron. Nuclear fission rarely occurs spontaneously. Nuclear fission occurs when an unstable nucleus splits into two or more pieces. What is fissionfusion and why is it important Grouping among animals. ![]()
