Because lead -206 is stable.
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.
There are about 110 elements found in the Periodic Table.... is it the same as decay chain?
One element decaying into another, which decays into another
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.
In Scotland, fluoride is added to water to help prevent tooth decay. This is a common practice in many countries to improve dental health in the population.

Only the end product of the decay chain of uranium, a non radioactive isotope of lead.
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.

When the element is stable. (apex)
Radioactive decay does not entirely stop. It continues until all the unstable radioactive isotopes have decayed into stable isotopes. The rate of decay may decrease over time, but it never completely stops.
One element decaying into another, which decays into another
A radioactive decay chain ends when a series of radioactive isotopes transforms into a stable isotope, which no longer undergoes further decay. Each isotope in the chain decays into another isotope or element until a stable state is reached. Once the final stable isotope is formed, the chain ceases, as there are no further radioactive transformations. This stable isotope can exist indefinitely without undergoing radioactive decay.
Isotopes of lead
The end products of uranium isotopes decay chain are the isotopes of lead.

The process is called decay, or sometimes nuclear decay. A link can be found below.
