They have a different number of neutrons in their nucleus: 143. 146 and 147, respectively.
Yes, they are different.
Yes
There are many isotopes for uranium, the most abundant of them in nature are:Uranium- 234, having 142 neutron and 92 protonUranium- 235, having 143 neutron and 92 protonUranium- 238, having 146 neutron and 92 protonThe abundance of these three isotopes in natural uranium is:Uranium-234: 0.006 %Uranium-235: 0.720 %Uranium-238: 99.274 %
Not uranium 239, but uranium 235 and plutonium 239.
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.
Uranium 235 and Plutonium 239 are fissile elements, fissionable with thermal neutrons.
Mostly Uranium 235, Uranium 238, and Plutonium 239 Also fission fragments. If your talking about any kind of radiation then it would be thermal radiation from the heat blast. When you split the Uranium atom you get 2 Neutrons, 2 protons + 2 fission fragments. 1 of the 2 neutrons will be uranium 235 and the other plutonium 239. the radiation from a nuclear blast will at first be heat. This will be continious until the energy that created it is depleated. Note Uranium 238 is weaker than Uranium 235 and it absorbs neutrons. Uranium 235 has a far greater Neutron density (99.3%) Uranium 238 = (0.7%)
I LIKE PIGS IN A BLANKET I think ,because when hit Uranium-238 by a neutron, it becomes uranium-239, an unstable isotope which returns into neptunium-239, which then itself decays, with a half-life of 2.355 days, into plutonium-239. ------------------------ Differences in nucleus stability and nuclear cross sections for fission with thermal neutrons.

Yes, plutonium-239 emits alpha particles by decay.
Pu-239
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
Uranium-238 is a fertile nuclear material that is useful in producing fissile material (Plutonium 239)
The only nuclei which are split are Uranium-235 in new fuel, and plutonium-239 which is formed during operation from U-238.
Uranium 235....but Uranium 238 is also present and will absorb a neutron and become Plutonium 239 and adds approximately 10% of the net power in most commercial fuels used in the USA. Most people are not aware that a reactor produces many transuranic elements, not just Plutonium, and that all of these elements have isotopes suitable for reactor fuel.
