Th-230 -> He-4 + Ra-226
Thorium which alpha decays produces an alpha particle (Helium 4) and a Radium-226 atom.
238U --> 234Th + 4He 234Th --> 234Pa + e- 234Pa --> 234U + e- 234U --> 234Np + e-, not possible
bismuth 210 decays by beta decay to polonium 210 that decays by alpha decay to lead 206
An alpha particle is emitted when Pu-240 decays to U-236. It consists of two protons and two neutrons and is commonly emitted in alpha decay processes.
Alpha decay is involved when polonium-214 decays into lead-210. In alpha decay, an alpha particle (2 protons and 2 neutrons) is emitted from the nucleus, reducing the atomic number by 2 and the mass number by 4.
An Alpha particle, and associated gamma radiation from the excited nucleus.
This is the isotope of uranium - U-238.
238U radiates alpha particles and decays via 234Th and 234Pa into 234U, which has a halflife of 245,500 years. (Thorium-234, Protactinium-234, Uranium-234 respectively)
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.
238U --> 234Th + 4He 234Th --> 234Pa + e- 234Pa --> 234U + e- 234U --> 234Np + e-, not possible

Alpha and beta decays.
An alpha particle is emitted when Pu-240 decays to U-236. It consists of two protons and two neutrons and is commonly emitted in alpha decay processes.
Go nnn and the other one and get it.
Alpha decay is involved when polonium-214 decays into lead-210. In alpha decay, an alpha particle (2 protons and 2 neutrons) is emitted from the nucleus, reducing the atomic number by 2 and the mass number by 4.
An Alpha particle, and associated gamma radiation from the excited nucleus.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
During each alpha decay, a helium nucleus (alpha particle) is emitted, decreasing the atomic number by 2 and the mass number by 4. Protactinium-229 undergoes two alpha decays to form Francium-221. The process of alpha decay involves the emission of alpha particles from the nucleus of an atom.
