Thermal neutrons (0,025 eV = 2 200 m/s) cause nuclear fission of the atom of the isotope 235U, releasing a great energy (202,5 MeV for one atom).
Sodium-24 would be formed if magnesium-24 is bombarded with a neutron and then ejects a proton. The neutron is absorbed to form magnesium-25, which then decays by emitting a proton to become sodium-24.
When an atom is bombarded by a neutron, it may absorb the neutron and become unstable. This can lead to the nucleus undergoing a process called neutron capture, forming a new isotope of the same element through nuclear transmutation. The new isotope may be radioactive and undergo radioactive decay to achieve stability.
The resulting isotope is uranium 239 with a half life of 23.5 minutes (beta desintegration).
The atomic number of uranium is 92, so its atoms have 92 protons in their nuclei. If uranium-235 absorbs a neutron, it would then have the mass number of 236. The number of neutrons is the mass number minus the atomic number, so the number of neutrons in the uranium-236 nuclei would be 236-92=144.
Beryllium is the first member of the group in the periodic table and can be used as a neutron source due to its ability to produce neutrons when bombarded with alpha particles.
The nuclear reaction is: 23892U + n-------23992U-------23993Np + e--------23994Pu + e
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.
The other product formed when curium-242 is bombarded with an alpha particle is uranium-238.
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.

This depends on a lot of things. When a neutron collides with an uranium atom, it might bounce off, cause the atom to decay, or be captured into the atom. But which it does depends on the isotope of the atom, the temperature of the atom, and the velocity of the neutron. My understanding is that it can cause any isotope of uranium to decay, and certainly it can bounce off any, but it can only be captured by U233, U234, or U235; the other isotopes of uranium, U236, and U238, will not capture neutrons. The interactions of various isotopes of different temperatures with neutrons of different velocities is complicated, and no simple rule about it can be stated.
A uranium-235 nucleus must absorb a neutron in order to become unstable and split, a process known as nuclear fission. This absorption of a neutron causes the uranium-235 nucleus to become uranium-236, which then splits into two smaller nuclei, releasing additional neutrons and a large amount of energy.
uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
The answer is neutron. :)
the uranium isotope 335 is the "uranium" you are thinking of. uranium 335 is bombarded with one neutron. this turns it into uranium 336 which is extremely unstable. the isotope splits into krypton and barium, and three neutrons. but two neutrons are converted into energy.
the uranium is the thing which helps to make atomic energy on uranium atoms the neutrons are bombarded and its cycle is continued bcoz on bombarding one neutron on uranium it takes place with 3 neutrons and some heat
