Fissile, that is they will split on capturing a neutron, releasing energy. Also if the fission releases more neutrons, as with U-235 and Pu-239, this gives the possibility of a chain reaction.
Firing a neutron at the nucleus of the atom.
FISSION. nobody on this website knows the answer..... SHAME
Only certain elements are fissionable, or at least with practical means. The fission of for example the atom U235 happens when it is struck by a slow neutron, it splits, which is fission, releasing two smaller atoms and two or three neutrons (products). The products from the nuclear reaction weigh less then the original atoms. The difference in weight is converted into energy.
atoms can be split from a molecule in two ways: through a chemical reaction in which the atoms split off a molecule and re-form to make a new one, or by an induced fission reaction.
Nuclear fusion is the process of squeezing two lighter atoms together to make heavier atoms; nuclear fission is the process of splitting heavier atoms into lighter ones. In both processes, some of the mass of the original atoms are converted into energy; fusion tends to convert more mass into energy than fission does, so fusion tends to create more energy. Heavier atoms needed for a fission chain reaction tend to be unstable and radioactive, and thus the fission process tends to produce more radioactivity.
The nuclear reaction when atoms split is called fission. Fission is where atoms split into smaller particles or atoms.
Firing a neutron at the nucleus of the atom.
Nuclear fission
the atoms split and cause a chain reaction
The products are very different.

In such a case nuclear fission occurs.

The splitting of nuclei of atoms is called nuclear fission. This process is categorized as either a nuclear reaction or a radioactive decay reaction.
-- changes to the nuclei of the atoms involved -- the conversion of mass to energy
The uranium 235 atoms in the nuclear fuel are what actually fission, or split into two other atoms. The uranium is in ceramic fuel pellets that are inserted into fuel rods, that make up fuel elements, that are in the reactor core that is located in the reactor vessel of the nuclear power plant. After the fuel has been in the reactor it begins to produce plutonium 239 atoms within the fuel which will also undergo a fission reaction.
