Hint: Nuclear fusion would be defined as the joining of two or more small atoms to form one large atom whereas nuclear fission would be defined as the division of a single atom into multiple atoms of small size.
Complete step-by-step answer:
Note: In fusion two or more atoms make one large atom and in fission one atom gets disintegrated into two or more smaller atoms students usually get confused between fusion and fission. In nuclear fusion hydrogen isotopes are used as fuel. And in nuclear fission uranium is one of the widely used fuels. In case of nuclear fusion High density and high temperature is needed for the reaction to take place, whereas in nuclear fission there is a necessity to have a critical mass of substance and neutrons moving with high speed.
Complete step-by-step answer:
| Basis | Nuclear Fission | Nuclear Fusion |
| The necessity for energy | The amount of energy released in a nuclear fission reaction is much lower than the energy released during fusion. | The release of energy during nuclear fusion reaction is way higher than that of the fission reaction. |
| Production or usage of energy | Nuclear power plant uses this technology to produce energy | Power plant related experiments use this technology. |
| Necessity for these energies | It requires less energy to divide one atom into two or more parts | It requires a huge amount of energy to combine two or more atoms into one single atom. |
| Reactions which takes place naturally | This type of reaction never occur in normal cases | This type of reaction takes place in the sun and stars. |
| Outcome of these reactions | The nuclear fission reaction produces substances that are highly radioactive. | In very few nuclear fusion reactions radioactive chemicals come out of. |
