It takes a little energy to split an atomĮxtremely high energy is required to bring two or more protons in close approach with each other It is necessary to have a critical mass of the substance with high-speed neutrons for a nuclear fission process to occurĪ higher density with an environment of high temperature is necessary for the process of nuclear fusion

The process of fusion can be observed in stars such as the sunīy-products formed after the reaction takes placeĪ lot many highly radioactive particles are generated after fissionĪ very few radioactive particles are produced in the process of nuclear fusion, however, when the “trigger” fission is used then the formation of radioactive particles take place This cannot be observed in nature as fission does not occur naturally Nuclear fusion is the combination of two or lighter atoms to form a larger one Nuclear Fission refers to the splitting of one atom into two or more daughter atoms (lighter atoms) The Distinction between Nuclear Fission and Nuclear Fusion in Tabular form: Consider two train bogies joining or fusing via a magnet. The nuclear fusion process is endothermic because it requires absorbing energy to fuse two atoms. The term 'nuclear fusion' refers to the process by which two or more atoms combine to form a larger atom. The term "fuse" refers to the joining of two or more objects. When the nuclear fission process breaks, a large amount of energy is released, indicating that the nuclear fission process is exothermic. These small atoms are technically light in their weight. In this context, nuclear fission refers to the breaking or splitting of a large or parent atom into smaller ones, or two or more daughter atoms. The term "fission" clearly denotes the splitting or breaking of something into smaller pieces. What is the Distinction between Nuclear Fission and Nuclear Fusion? Similarly, when a source of energy (light) splits into quanta or photons, this is referred to as the nuclear fission process. When two highly active atoms collide and fuse to form a larger atom due to the strong inter-atomic force of attraction, this is referred to as nuclear fusion. By considering the following scenario, we can distinguish between nuclear fission and nuclear fusion. The process of nuclear fusion is as opposed to that of nuclear fission.
