Answer:
When does the radioactive decay of a radioisotope stop? Give one example. An unstable isotope continues the decay process until it reaches a stable form. One example is the decay of carbon-14 to nitrogen-14.
Explanation:
For example, Uranium-238 is a radioactive isotope that undergoes decay by releasing an alpha particle and, as a result, gives rise to a pro of Thorium-234.
Series (or family) of natural radioactive decay is the set of elements with unstable nucleus, which follow an orderly sequence of spontaneous decay, that is, they emit alpha and beta particles, until a stable lead nucleus is created.
This phenomenon is called natural radioactive decay because it occurs spontaneously when the unstable nucleus releases alpha (α), beta (β) and/or gamma (γ) particles.
