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.
What makes a fission reaction possible is that certain atoms are unstable. In particular, heavy isotopes like uranium-235 and plutonium-239 can undergo fission when they absorb a neutron, leading to their nucleus splitting into smaller fragments along with the release of a significant amount of energy. This instability is key to initiating and sustaining a fission chain reaction.
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.
Nuclear fission reactions in certain atoms can be initiated through processes such as bombarding the atoms with neutrons or by using controlled conditions that allow for the splitting of atomic nuclei. These processes can trigger a chain reaction leading to the release of energy, which can be harnessed for various applications, including nuclear power generation.
When atoms split, particularly in a process called nuclear fission, they produce smaller atoms, known as fission products, along with a significant amount of energy and neutrons. This reaction releases energy due to the conversion of mass into energy, as described by Einstein's equation (E=mc^2). The released neutrons can further induce fission in nearby atoms, potentially leading to a chain reaction.
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.
What makes a fission reaction possible is that certain atoms, such as uranium and plutonium, are unstable and capable of splitting into smaller atoms when struck by a neutron. This process releases a large amount of energy in the form of heat and additional neutrons, which can go on to trigger more fission reactions in a chain reaction.

The nuclear reaction when atoms split is called fission. Fission is where atoms split into smaller particles or atoms.

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.
