How does a fusion reaction differ from a fission reaction?

Answer:
hi hi here is your answer hope you will like it and make me brainlist
Explanation:
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
Nuclear Fusion vs Fission
Basis
Nuclear Fusion
Nuclear Fission
Definition
Fusion would be defined as the joining of two or more small atoms to form a large atom.
Fission would be defined as the division of a single atom into multiple atoms of small size.
The necessity of Energy
A massive amount of energy is required to combine small atoms to form a large atom.
Requires less energy to divide atoms into two or more ones.
The release of Energy
The release of energy during fusion is way higher than that of the fission reaction.
The amount of energy released in fission is much lower than the energy released during fusion.
Production/Usage of energy
Experiments in power plants use this technology.
The energy produced in nuclear power plants uses this technology.
Natural Reactions
Takes places in stars and the Sun that are natural forces.
Never occurs in nature in normal cases.
Ideal Conditions
High density and high-temperature atmosphere are the requirements.
There is a necessity to have a critical mass of the substance and neutrons with high speed.
Reaction Outcome
Very few radioactive chemicals come out of this reaction.
The fission reaction produces highly radioactive substances.
Fuel Used
Hydrogen isotopes are used as fuel in experimental plants.
Uranium is one of the primary fuels in nuclear power plants.
