Expert Answer
| Basis | Nuclear Fission | Nuclear Fusion |
| Definition | Fission would be defined as the division of single atom into multiple atoms of small size. | Fusion would be defined as the joining of two or more small atoms to form a large atom. |
| The necessity of Energy | Requires less energy to divide atoms to two or more ones. | Huge amount of energy required to combine small atoms to form a large atom. |
| The release of Energy | The amount of energy released in fission is much lower than the energy released in fusion. | The release of energy in fusion is way higher than that of the fission reaction. |
| Production/Usage of energy | Used to produce energy in nuclear power plants. | The technology is used for experiments in power plants. |
| Natural Reactions | Never occurs in nature in normal cases. | Happens in natural forces like stars and sun. |
| Ideal Conditions | There is a necessity to have a critical mass of the substance and neutrons with high speed. | Requires high density and high-temperature atmosphere. |
| Reaction Outcome | The fission reaction produces highly radioactive substances. | Very few radioactive chemicals come out of this reaction. |
| Fuel Used | Uranium is one of the primary fuels in nuclear power plants. | Hydrogen isotopes are used as fuel in experimental plants. |
example of nuclear fusion
2 1Deuterium + 3 1Tritium = 42He + 10n + 17.6 MeV
Example of nuclear fission
23592U + n = 23692U
followed by
23692U = 14456Ba + 89 36Kr + 3n + 177 MeV
