[Answer] Which particles that make up an atom are involved in nuclear reactions?

Answer: protons and neutrons

Most relevant text from all around the web:

Which particles that make up an atom are involved in nuclear reactions? In the initial collision which begins the reaction the particles must approach closely enough so that the short range strong force can affect them. As most common nuclear particles are positively charged this means they must overcome considerable electrostatic repulsion before the reaction can begin. Even if the target nucleus is part of a neutral atom the other particle must penetrate well beyond the electron cloudand closely approach the nucleus which is positively charged. Thus such particles must be first accele… Alpha particles also called alpha rays or alpha radiation consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay but may also be produced in other ways. Alpha particles are named after the first letter in the Greek alphabet α. The symbol for the alpha particle is α or α2+. Because they are identical to … Nuclear fission - Wikipedia Nuclear reaction - Wikipedia Nuclear reaction - Wikipedia Nuclear reaction - Wikipedia The energy of nuclear fission is released as kinetic energy of the fission products and fragments and as electromagnetic radiation in the form of gamma rays; in a nuclear reactor the energy is converted to heat as the particles and gamma rays collide with the atoms that make up the reactor and its working fluid usually water or occasionally heavy water or molten salts. A nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions thus leading to the possibility of a self-propagating series of these reactions . The specific nuclear reaction may be the fission of heavy isotopes (e.g. uranium-235 235 U). The nuclear chain reaction releases several million times more energy per reaction than any ... Nuclear reactions can change one nuclide into another. See table of nucl...
