Nuclear fission describes a nuclear reaction in which a heavy nucleus, such as uranium, is bombarded by neutrons causing the atom to

split into two or more smaller atoms. The fission reactions take relatively little energy input to occur and do not occur in nature.

Fission produces many highly radioactive particles and releases large amounts of energy.

Predict the changes in the nucleus as uranium-235 is split in a nuclear reactor.

Energy decreases as two stable atoms are formed and gamma radiation

discharges

Splitting uranium-235 decreases the energy and emits positron and beta

particles.

Uranium-235 splits into barium-141 and krypton-92 and alpha radiation is

emitted

When uranium-235 is split, three neutrons and a large amount of energy -

are released
