There are 3 naturally occurring isotopes of Uranium, all decay by alpha to Thorium:
The equation for the alpha decay of 234U is: 92234U --> 90230Th + 24He representing the alpha particle as a helium nucleus. 234U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
Plutonium-241 decays by both beta- and alpha decay. For beta- decay the equation is ...94241Pu -> 95241Am + e- + v-eNot asked but answered for completeness sake, for alpha decay the equation is ...94241Pu -> 92237U +24He2+

A:Uranium - 238 --> Pb - 206 + Alpha + Beta note this is a simplified over all reaction, the actual process involves around 15 steps...A:The equation for the alpha decay of 238U is: 92238U --> 90234Th + 24HeThe alpha particle is represented as an He nucleus.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
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.
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 234U is: 92234U --> 90230Th + 24He representing the alpha particle as a helium nucleus. 234U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.
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)
parent element
Uranium has a different decay chain/series for its different isotopes. Uranium 238 for example first decays to thorium 234 through alpha decay while U235 alpha decays to thorium 231. Both have different half lifes which can be found on a natural decay series chart for the said element. The thorium in either case then beta decays to another element.
Plutonium-241 decays by both beta- and alpha decay. For beta- decay the equation is ...94241Pu -> 95241Am + e- + v-eNot asked but answered for completeness sake, for alpha decay the equation is ...94241Pu -> 92237U +24He2+
bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
The first step is an alpha decay to (guess what!) uranium 235. You can probably take it from there.
Lead-210 decays by alpha or beta decay. The equation for the alpha decay of 210Pb is: 82210Pb --> 80206Hg + 24He representing the alpha particle as a helium nucleus. The equation for the beta decay of 210Pb is: 82210Pb --> 83210Bi + -10e where the -10e is an electron.
Uranium 238 is transformed in thorium 234 by alpha decay.
