Uranium 238 is transformed in thorium 234 by alpha decay.
It is thorium 234.
The decay of a uranium-238 atom into lead-206 involves the emission of 8 alpha particles. This decay process releases 8 helium-4 (α) particles as the uranium nucleus undergoes multiple decay steps to stabilize as lead-206.
Radium naturally decays into radon, which is a radioactive noble gas. This decay process is one of the steps in the radioactive decay chain of uranium-238.
The daughter nuclide resulting from the decay of uranium-235 through an alpha decay followed by a beta decay is thorium-231.
Uranium-239 does NOT decay by alpha decay, it decays only by beta and gammadecay.
Uranium 238 is transformed in thorium 234 by alpha decay.
The end products of uranium isotopes decay chain are the isotopes of lead.
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
See the link below for radioactive decay chains.
Alpha decay
It is thorium 234.
Lead isotopes are a natural result of uranium decay. As uranium undergoes radioactive decay, it eventually transforms into stable lead isotopes. Therefore, the presence of lead in uranium deposits is a byproduct of this decay process.
The possible products of the alpha decay of uranium-238 are thorium-234 and helium-4. During alpha decay, the uranium nucleus releases an alpha particle (helium nucleus) and transforms into thorium-234.
The decay of a uranium-238 atom into lead-206 involves the emission of 8 alpha particles. This decay process releases 8 helium-4 (α) particles as the uranium nucleus undergoes multiple decay steps to stabilize as lead-206.
When plutonium-239 loses an alpha particle through decay, it transforms into uranium-235.
Radium is a decay product of uranium.
