Uranium-237 will undergo beta minus decay to neptunium-237 according to the following equation: 92U237 => 93Np237 + e- + 0.519 MeV At the risk of being a bore, a neutron in U237 undergoes a weak interaction-mediated change into a proton and an electron. The electron will be ejected from the nucleus immediately. Along with the electron, which leaves with a lot of kinetic energy, we'll see an antineutrino and the decay energy (0.519 MeV).
Uranium 238 is transformed in thorium 234 by alpha decay.
Uranium 238 goes through a decay series until it becomes lead. An intermediate product of this decay series is Thorium 234. Uranium 238 decays into an atom of Thorium 234 and an atom of Helium 4. The Helium 4, being a gas, frequently escapes into the atmosphere. Since the decay of Uranium 238 into Thorium 234 and Helium 4 gives off heat and mass, nature does not normally reverse the process.
Uranium slowly decay to form the stable nucleus of Lead after a series of nuclear reactions.
It is thorium 234.
Radon is a natural chemical element; it can be found inthe radioactive decay series of uranium, thorium.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
parent element
There are 3 naturally occurring isotopes of Uranium, all decay by alpha to Thorium:238U --> 234Th + 4He235U --> 231Th + 4He234U --> 230Th + 4He
The first step is an alpha decay to (guess what!) uranium 235. You can probably take it from there.

The equation for the alpha decay of 233U is: 92233U --> 90229Th + 24He representing the alpha particle as a helium nucleus. 223U can also undergo fission, but since this is an rather unpredictable process, there is no standard equation.
The equation for the alpha decay of 235U is: 92235U --> 90231Th + 24He representing the alpha particle as a helium nucleus. 235U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
The equation for the alpha decay of 233Pu:94233Pu --> 92229U + 24He2+where the alpha particle is represented as a helium nucleus.Note that 233Pu decays by alpha decay with a probability of only 0.12%. The other 99.88% is Beta+ decay.
Uranium-237 decays by beta- decay to Neptunium-237 with a half-life of 6.75 days, emitting a W- boson which then decays to an electron and an electron antineutrino... 92237U --> 93237Np + (W- --> e- + v-e)
Uranium 238 is transformed in thorium 234 by alpha decay.
If a uranium-244 atom undergoes alpha decay, it will become an atom of thorium-240. If we wrote an equation, it might look like this:92244U => 90240Th + 24He++The uranium-244 is transmuted into throium-240, and the alpha particle, which is a helium-4 nucleus (and represented as such) emerges at the tail end of the equation.
