They are many but the most famous three are: uranium-233, Uranium-235, and Plutonium-239.
Another answerUranium-235, uranium-238, and plutonium-239 are all capable of undergoing neutron induced fission. Actually there are other isotopes that also do this, but they are not commonly used as fuel.

What three isotopes that can undergo nuclear fission?
Three isotopes that can undergo nuclear fission are uranium-235, plutonium-239, and uranium-233. When these isotopes absorb a neutron, they become unstable and split into smaller fragments, releasing energy in the process.
What is fission cross section in nuclear reactor?
The fission cross section in a nuclear reactor is a measure of the probability that a neutron will induce fission in a particular nucleus. It is a crucial parameter for determining the neutron flux and reaction rates within the reactor core. Different isotopes have different fission cross sections depending on their ability to undergo fission when struck by a neutron.
Atoms that naturally undergo nuclear fissions are called?
These are called fissile or fissionable. Fissile isotopes undergo fission, producing sufficient neutrons of sufficient power that a chain reaction can happen, if there is enough of the isotope to support it. The mass sufficient to support a chain reaction is called critical. Atoms of fissionable isotopes will undergo fission when a sufficiently energetic neutron collides with them, but the neutrons they emit when they divide are either insufficient in number or insufficient in energy to sustain an chain reaction. There is a third type of material that can undergo fission, called fertile, which is isotopes that can be caused to capture neutrons, changing into fissile or fissionable isotopes, so the fission does not happen to atoms of the fertile material directly, but to the atoms of the isotopes they become.
Is it true that the daughter products of nuclear explosions produce heavy but stable isotopes of uranium?
No, the daughter products of nuclear explosions do not produce stable isotopes of uranium. Instead, uranium isotopes can undergo fission or neutron capture to form various other radioactive isotopes as byproducts.
What does it means if an isotope is fissile?
If an isotope is fissile, it means that it can undergo nuclear fission reactions when bombarded by neutrons. This process releases a large amount of energy and more neutrons that can sustain a chain reaction. Fissile isotopes are commonly used in nuclear reactors and weapons.

What is the bullet that starts a fission reaction?
The bullet that starts a fission reaction is a neutron. When a neutron collides with the nucleus of a fissile isotope, such as uranium-235, it can induce the nucleus to undergo fission, releasing more neutrons and a large amount of energy.
What causes a splitting nucleus?
The capture of a neutron can split a nucleus - but only for certain isotopes like U-235 and Pu-239. Two naturally occurring isotopes undergo spontaneous fission, meaning the nucleus splits without neutron capture. These are 235U and 238U. A few other isotopes undergo spontaneous fission, but these are produced by an earlier neutron capture. Spontaneous fission is the result of quantum tunnelling, which is rather difficult to explain. There are related links below.

How is a uranium-235 nucleus made to undergo fission?
Nuclear fission is the splitting up of big atomic nuclei. Uranium is quite a large nuclei. Each time a uranium atom splits up, it spits out two or three neutrons. One of which might hit another nuclei causing it to split - thus keeping the chain reaction going. The uranium atom - when hit by a neutron splits into Barium and Krypton.
How many neutrons are there when uranium 235 is bombarded with a neutron?
When uranium-235 is bombarded with a neutron, it may undergo a fission reaction, resulting in the formation of multiple fission products, which may include different numbers of neutrons depending on the specific reaction that takes place. Typically, fission of uranium-235 produces around 2 to 3 neutrons per fission event.
Animals that undergo binary fission?

What does it mean if a isotope is fissile?
A fissile isotope is one that can undergo fission when struck by a neutron, releasing energy and more neutrons that can then cause further fission reactions. This property is essential in nuclear reactors and nuclear weapons. Examples of fissile isotopes include uranium-235 and plutonium-239.
Is xenon radioactve?
Some isotopes of xenon do undergo radioactive decay to caesium.
