No. Often a decay product is itself unstable and will decay into something else until a stable isotope is reached. This is called a decay chain.
For example, Uranium-238 will decay 15 times through various isotopes until it becomes lead-206 which is stable
No, the parent element in a nuclear reaction is not always radioactive. While many parent isotopes are indeed radioactive and decay into stable or unstable daughter isotopes, there are also stable isotopes that can undergo nuclear reactions without being radioactive themselves. For example, stable isotopes can be involved in nuclear reactions such as neutron capture or fusion, but they do not decay over time like radioactive isotopes.
No, the daughter products of nuclear explosions do not produce stable isotopes of uranium. Instead, uranium isotopes can undergo fission or neutron capture to form various other radioactive isotopes as byproducts.
False. When an unstable isotope decays, the resulting daughter isotope may or may not be stable. Some daughter isotopes are stable, while others may still be radioactive and undergo further decay.
A radioactive rock will never become completely stable because it contains unstable isotopes that decay over time, emitting radiation. This decay process continues until the isotopes transform into stable daughter products, but the original rock may always contain a mix of both radioactive and stable elements. Additionally, the rate of decay varies for different isotopes, meaning some will take much longer to reach stability than others. As a result, the rock will always retain some level of radioactivity throughout its existence.

Naturally occurring scandium 45Sc is stable. However synthetic isotopes of scandium can have 36 to 60 nucleons. Isotopes with masses above the stable isotope decay through beta emission into isotopes of titanium. Isotopes below the stable variety decay, mainly by electron capture, into isotopes of calcium.
Radioactive isotopes are not stable.
Stable isotopes are used as tracers.
copper has 2 stable isotopes
Hydrogen-1 and hydrogen-2 isotopes are radioactively stable.

No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
