Question

Nuclear fission is the process in which a uranium atom is split and energy is released.
Nuclear fission is the process in which fossil fuels are subjected to a large amounts of radiation, and as a result, energy is released.
Nuclear fission is the process which anything is divided into two parts.
Nuclear fission is a renewable energy resource that is used to create electricity.

Answer 1

Nuclear fission is a type of nuclear reaction where the nucleus of an atom splits into two or more smaller nuclei, along with the release of a large amount of energy. This process is typically initiated by bombarding a heavy atomic nucleus, such as uranium or plutonium, with neutrons. The energy released in nuclear fission reactions is used in nuclear power plants to generate electricity.
