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.
Yes
The average number of neutrons per nuclear fission is 2,5.
Nuclear fission. It realeases nuclear energy by spitting big atomic nuclei, usually those of uranium. Neutrons are fired at the nuclei. As the neutrons smash into the nuclei they split off more neutrons, which bombard other nuclei, setting of a chain reaction, which makes energy.
Nuclear fission means that in this process the heavy nuclei are split into fragments (or fission products) when bombarded by neutrons and results in release of energy.
An isotope means an atom with the same amount of electrons and protons, but with different amount of neutrons.Relative weight of a neutron is 1, a proton is 1, and an electron is very small. So weight of an atom is approx. mneutrons + m protons.So, an uranium-235, as U is the 92th atom in periodic table, contains 92 protons, 92 electrons to be chargeless, and 143 (=235-92) neutrons.An uranium-238, from the definition of isotope, contains 92 protons, 92 electrons, and 146 (=238-92) neutrons.The difference is the 3 neutrons.
Yes
Nuclear fission
The average number of neutrons per nuclear fission is 2,5.
Under bombardment with thermal neutrons a nuclear fission is produced with the isotopes 235U and 233U; a formidable energy is released after fission.
The fission of uranium-235 nuclei
Nuclear fission. It realeases nuclear energy by spitting big atomic nuclei, usually those of uranium. Neutrons are fired at the nuclei. As the neutrons smash into the nuclei they split off more neutrons, which bombard other nuclei, setting of a chain reaction, which makes energy.
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.
Nuclear fission means that in this process the heavy nuclei are split into fragments (or fission products) when bombarded by neutrons and results in release of energy.

This process is called nuclear fission.
the kind of energy produced when billions of atomic nuclei from uranium are split in a fission reacion
The uranium nucleus has 92 protons, 92 electrons an a different number of neutrons, specific for each isotope.
