Nuclear fission has actually occured naturally throughout our planet's history. We know this because we can see the fission particles (particles that appear as a byproduct of fission) in uranium deposits.
About 2 billion years ago, a self sustaining fission reaction began in what is now Central Africa and is believed to have lasted several hundred thousand years.
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
Nuclear fission reactions involve the splitting of atomic nuclei to release energy, while nuclear fusion reactions involve combining atomic nuclei to release energy. Both types of reactions are seen in nuclear power plants and stars.
Nuclear energy is produced in the core of a nuclear reactor, where controlled nuclear fission reactions occur. These reactions release heat energy, which is then used to generate electricity through steam turbines.
Nuclear fusion reactions can generate the most energy compared to other types of nuclear reactions. Fusion involves combining light nuclei to form heavier nuclei, releasing large amounts of energy in the process. This is the same process that powers the sun and other stars.
All nuclear reactions involve changes in the structure of atomic nuclei, which can result in the release of a large amount of energy. These reactions are governed by the principles of conservation of mass and conservation of energy. Additionally, nuclear reactions can involve the splitting (fission) or combining (fusion) of atomic nuclei.
The object of nuclear chemistry is the study of radioactive materials, nuclear wastes, chemical reactions in a nuclear reactor etc.
No, nuclear chain reactions can happen in several types of fissile materials, not just uranium. Other examples include plutonium and thorium. These materials can undergo fission reactions and sustain a self-sustaining chain reaction.
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
Nuking the sun is not possible with current technology. However, theoretically, if it were possible, the sun is so massive that a nuclear explosion would have negligible impact on it. The sun's nuclear fusion reactions are much more powerful than any man-made nuclear explosion.
The nuclear reactions in the Sun primarily involve fusion of hydrogen nuclei to form helium, releasing energy in the process. In a nuclear reactor, the reactions typically involve fission of heavy nuclei like uranium or plutonium, releasing energy through splitting these nuclei. The conditions and mechanisms governing the reactions in the Sun and in a nuclear reactor are different due to the vastly varying scales and environments of the two systems.
nuclear fission and nuclear fusion

Nuclear Fusion. This process involves 'fusing' together two smaller nuclei to form a bigger nucleus.
Nuclear decay is the spontaneous process where an unstable nucleus emits particles or energy to become more stable. Nuclear transformation reactions involve bombarding a nucleus with particles to alter its composition or create new nuclei. Decay is a natural process, while transformation reactions are induced.
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
Nuclear reactions at very high temperatures are known as thermonuclear reactions. These reactions involve the fusion of atomic nuclei, typically hydrogen isotopes, and release large amounts of energy. Thermonuclear reactions are responsible for the energy production in stars like our sun.
A controlled nuclear reaction is one in which the average number of reactions per second does not increase.
