The release of excess binding energy.
Uranium-235 react with thermal neutrons in a nuclear reaction called fission. The enormous energy released by the nuclear fission can be transformed in electricity and heat in nuclear reactors.
A nuclear bomb or atomic bomb
nuclear fission
This nuclear weapon is called an atomic bomb or a nuclear bomb
It is called nuclear chain fission reaction.
This is due to the fact that the forces between nucleons are very strong - much stronger than the forces between atoms in a chemical reaction for example.
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
In a nuclear fission reaction, the energy comes from the splitting of atomic nuclei.
Splitting of atomic nuclei, also known as nuclear fission, is a nuclear reaction in which the nucleus of an atom is split into smaller parts. This process releases a significant amount of energy in the form of heat and radiation. Nuclear fission is used in nuclear power plants and nuclear weapons.
In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
A nuclear fission reaction occurs in a nuclear power plant. This is the process where the nucleus of an atom is split, releasing large amounts of energy in the form of heat, which is used to generate electricity.
During the detonation of a nuclear bomb an enormous amount of energy is released as fission due to the splitting (fissioning) of atoms of uranium or plutonium. In the case of a simple nuclear weapon (such as those dropped on Japan during World War 2) this is where the explosion stops. In the case of a hydrogen bomb, also referred to as a thermonuclear weapon, the energy released by the fission is used to trigger the fusion of atoms of hydrogen, releasing energy in the same way that the sun produces energy.
