the breaking apart of atomic nuclei into smaller nuclei accompanied by the release of energy

The cleavage of a heavy nucleus into two nuclei of intermediate mass

A nuclear reaction in which a high-energy neutron bombards a heavy, unstable atomic nucleus, causing it to split into two smaller nuclei, and releasing some neutrons and a vast amount of energy at the same time.

The radioactive decay process in which isotopes split apart to create two smaller atoms.

the splitting of a nucleus into two smaller, approximately equal fragments, accompanied by the release of neutrons and a large amount of energy.

The division of the nuclei of isotopes of certain heavy elements, such as uranium and plutonium, effected by bombardment with neutrons. Nuclear fission causes the release of energy, additional neutrons, and an enormous quantity of heat. Nuclear fission is used in nuclear power plants and nuclear weapons. A by product of nuclear fission is toxic radioactive waste. See also nuclear fusion.

The splitting of a nucleus of a heavy element into two lighter nuclei, generally accompanied by the release of one or more neutrons and energy.

The splitting of an atomic nucleus into two large fragments.

relies on splitting heavy atoms (uranium and plutonium) into smaller elements (used to make the A-bomb)

The process in which the nucleus of a heavy atom splits into two or more parts, releasing energy and two or three free neutrons.

is the breakup of heavy nuceli into two medium mass nuclei with an accompanying release of energy. This form of nuclear instability ultimately limits the extent to which heavy nuclei can be synthesised. It places an upper limits on the atomic number (A) of nuclei produced by the r-process.

fission. Compare with nuclear fusion. Splitting of a nucleus into two smaller nuclei and neutrons. The smaller nuclei have higher binding energy than the original nucleus, and fission results in the release of energy.

A physical process which takes a nucleus of a heavy element (like Uranium or Plutonium, for example) and breaks them down into two or more smaller nuclei. This process releases large amounts of energy. It is sometimes called "Splitting the Atom". This is used in many modern power plants to generate electricity by heating water with the energy released. The two or more smaller nuclei which are produced are frequently toxic, and nearly always radioactive, which makes this method of producing electricity controversial. Fission is also the method used in simple nuclear weapons.

A nuclear reaction in which a nucleus is split into fragments, usually two pieces of comparable mass, accompanied by a release of energy.

A type of nuclear reaction in which the nucleus of an atom splits into two nearly equal parts, rather than ejecting one or a few small nuclear particles, as in most nuclear reactions.

The splitting of uranium isotopes to produce heat, which is then harnessed to produce electricity.

Nuclear fission occurs when a large unstable atom breaks apart via radioactive decay into smaller atoms and nuclear radiation. For example, uranium-235 is unstable and undergoes nuclear fission. Nuclear Power

The splitting of large atomic nuclei into into smaller ones, with the release of energy.

The splitting of an atomic nucleus, resulting in the release of large amounts of energy; the basic process a nuclear reactor uses to provide heat for the generation of electricity.

Atomic nuclear processes which involve the splitting of nuclei with the accompanying release of energy.

The splitting of a heavy nucleus, such as uranium, into two parts, releasing neutrons and energy. Nuclear fission is the process used in nuclear reactors, as well as in nuclear weapons.

The breaking up of a heavy nucleus in two parts of comparable masses, typically, 1/3 and 2/3 of the original mass, associated with a great release of energy. Since both fragments have a positive electric charge, they repel each other vigorously, causing them to be ejected with great speed in opposite directions. The kinetic energy of that motion, ultimately converted to heat, is the source of the "nuclear energy" of fission.

A synonym for fission.

Nuclear change in which the nuclei of certain isotopes with large mass numbers (such as uranium-235 and plutonium-239) are split apart into lighter nuclei when struck by a neutron. This process releases more neutrons and a large amount of energy. Compare nuclear fusion.

The process in which a heavy nucleus splits into nuclei of intermediate masses and one or more protons are emitted.

(or Fission) - Nuclear fission occurs when a neutron splits the nucleus of a large atom, such as U235, into two smaller nuclei, releasing energy and additional neutrons. The extra neutrons then split other nuclei, producing still more neutrons that split more nuclei, and so on. This process is called a nuclear chain reaction.

The process of splitting the nucleus of certain atoms (e.g. uranium) with the resultant release of heat and radiation, as in atomic bombs or nuclear reactors.

is the splitting of the nuclei of atoms to produce heat and generate electricity.
