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.
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.
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.
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
Fusion: smaller atoms are made into bigger atoms (2 Deuterium atoms -> 1 Helium atom) Fission: larger atoms are made into smaller atoms (1 Uranium 235 (Z=92) + 1 neutron -> 1 Krypton 92 (Z=36) + 1 Barium 141 (Z=56))
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.
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.

the atoms split and cause a chain reaction
The products are very different.
In such a case nuclear fission occurs.
nuclear fission
The splitting of nuclei of atoms is called nuclear fission. This process is categorized as either a nuclear reaction or a radioactive decay reaction.
The Chernobyl disaster involved a nuclear fission reaction. Fission is the process of splitting atoms to release energy, which is the fundamental reaction in nuclear power plants like the one at Chernobyl. Fusion, on the other hand, involves joining atoms together to release energy and is the process that powers the sun.
False. A nuclear reaction in which the nuclei of atoms join together is called fusion, not fission. Fusion is the process that powers the sun and hydrogen bombs. Fission, on the other hand, is when the nucleus of an atom is split into two or more smaller nuclei.
