When the element is stable. (apex)
Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
The end products of uranium isotopes decay chain are the isotopes of lead.
It would end in a stable isotope.
It must obviously end with a stable isotope - for if you get an unstable isotope, that means that it will continue decaying, thus, the chain doesn't end yet.
The final product is not radioactive.
The process is called decay, or sometimes nuclear decay. A link can be found below.
Usually called a 'decay chain', there is a series of radioactive decays which end with a stable isotope. Ex: uranium undergoes about 14 steps in the decay chain that ends with the formation of a stable isotope of Lead.
Yes, that's correct. The uranium decay chain ends with the stable element lead-206. As uranium-238 undergoes alpha and beta decay, it transforms through various radioactive isotopes before reaching lead-206, which is stable and not subject to further radioactive decay.
Branching decay occurs in the thorium series because there are multiple pathways for the decay of thorium nuclei. Thorium can decay through alpha decay, beta decay, gamma decay, and other processes, leading to different end products with varying probabilities. These branching decay pathways contribute to the overall complexity of the thorium decay chain.
Common elements in a decay chain include uranium, thorium, radium, radon, and polonium. These elements undergo radioactive decay to produce different isotopes and elements through a series of transformations.
The decay chain for U-238 stops at lead because lead-206 is a stable isotope, meaning it does not undergo further radioactive decay. Once uranium-238 undergoes a series of alpha and beta decays, it eventually reaches a stable isotope of lead, which ends the decay chain.
Lead-206 is a stable isotope, which means it does not undergo further radioactive decay. As a result, the decay chain stops at lead-206 because it does not have any unstable isotopes that it can decay into.
