Why does decay chain for radioisotope U-238 eventually stop at lead?

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.


Why does the decay chain stop at lead-206?

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.


How many different appear in the decay chain?

There are about 110 elements found in the Periodic Table.... is it the same as decay chain?


The uranium decay chain ends when the final disintergration product is the stable element?

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.


What is the decay product of uranium-238?

U-238 is the most abundant (99.3%) of the three naturally occurring isotopes of Uranium. The other two are U-235 and U-234.U-238 decays spontaneously to Thorium-234 by alpha particle emission. This decays by beta decay to Protactinium-234 and then that undergoes beta decay to become U-234.There are many more decay steps by alpha and beta emission. The end result is Lead-206 which is stable.The full path can be found in the Argonne National Laboratories Human Health Fact Sheet, August 2005, titled Natural Decay Series: Uranium, Radium, and ThoriumThis is found at:http://www.ead.anl.gov/pub/doc/natural-decay-series.pdf

How many different elements appear in the 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.
