Write 3 differences between nuclear fission and nuclear fusion Please do not cheat from any website or internet and give correct answer and fast
Answers
Answer:
Nuclear Fission Nuclear Fusion
Fission is the splitting of a large atom into two or more smaller ones. Fusion is the fusing of two or more lighter atoms into a larger one.
Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun.
Fission produces many highly radioactive particles. Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that.
Critical mass of the substance and high-speed neutrons are required. High density, high temperature environment is required.
Takes little energy to split two atoms in a fission reaction Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion.
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 place in stars and the Sun that is 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.
