difference between nuclear fission and nuclear fusion?
Answers
Answer:
Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. ... Nuclear fission releases heat energy by splitting atoms.

Nuclear Fusion: Nuclear Fusion is a reaction that occurs when two atoms combine together to form one or more different atomic nuclei and subatomic particles like protons and neutrons. An enormous amount of energy is released in this process and is greater than the nuclear fission reaction. Example: Fusion occurs in the sun where the atoms of (isotopes of hydrogen, Hydrogen-3, and Hydrogen-2) Deuterium and Tritium combine in a huge pressure atmosphere with extremely high temperatures to produce an output in the form of a neutron and an isotope of Helium.
Explanation:
Basis
Nuclear Fission
Nuclear Fusion
Definition
Fission would be defined as the division of a 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 into two or more ones.
A massive amount of energy is 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 during fusion.
The release of energy during fusion is way higher than that of the fission reaction.
Production/Usage of energy
The energy produced in nuclear power plants uses this technology.
Experiments in power plants use this technology.
Natural Reactions
Never occurs in nature in normal cases.
Takes place in stars and the Sun that are natural forces.
Ideal Conditions
There is a necessity to have a critical mass of the substance and neutrons with high speed.
High density and high-temperature atmosphere are the requirements.
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.
