A nuclear reaction is a process in which the nucleus of an atom is changed through the release or absorption of energy. This can happen naturally, through processes such as radioactive decay, or it can be induced through human intervention, such as in the case of nuclear power plants and weapons.
In a nuclear reaction, the nucleus of an atom is rearranged in such a way that a new, more stable nucleus is formed. This rearrangement can happen through the emission of particles, such as protons, neutrons, and electrons, or it can happen through the absorption of energy from another source.
One of the most common forms of nuclear reaction is nuclear fission, in which the nucleus of an atom is split into two or more smaller nuclei. This process releases a large amount of energy, which can be harnessed to generate electricity in nuclear power plants.
Another common form of nuclear reaction is nuclear fusion, in which two or more atomic nuclei are combined to form a larger, more stable nucleus. This process also releases a large amount of energy, and is the reaction that powers the sun and other stars.
Overall, nuclear reactions are complex processes that involve the rearrangement of the nucleus of an atom. While they can be harnessed to generate electricity and other forms of energy, they also have the potential to be highly dangerous, and great care must be taken to control and manage nuclear reactions.
