Nuclear fission produces energy for nuclear power and drives the explosion of nuclear weapons. Both uses are possible because certain substances called nuclear fuels undergo fission when struck by …

Nuclear fission is the process where the nucleus of an atom splits into two or more smaller nuclei and other particles. These particles can include neutrons, alpha particles (helium nuclei), beta …

Jan 2, 2026 · Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of …

Nuclear fission is the process used in today's nuclear power plants. It occurs when the nucleus—the central core of an atom—typically of a heavy element, such as uranium or plutonium, splits into two …

Jul 30, 2025 · Nuclear fission occurs when a large atom is split into smaller atoms, producing lots of heat and radiation. Nuclear fusion occurs when two nuclei combine to form a single nucleus, …

The fission of a single nucleus results in the production of 2 or 3 neutrons. These neutrons are capable of colliding with another nucleus to cause an additional fission reaction.

May 25, 2025 · Nuclear fission is the process by which the nucleus of an atom splits into two or more smaller nuclei, accompanied by the release of a large amount of energy. This seemingly …

Nuclear fission is a nuclear reaction or a decay process, in which the heavy nucleus splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in the form of …

Jul 19, 2023 · Fission is the process by which an atom splits into two, generating two smaller atoms and a tremendous amount of energy. Fission powers nuclear bombs and power plants.

Jun 9, 2025 · Fission is the splitting of an atomic nucleus into two or more lighter nuclei accompanied by energy release. The original heavy atom is termed the parent nucleus, and the …
