all but one.
No, there are many stable isotopes.
No isotope of silver ordinarily found in nature is radioactive. Like all elements, silver has synthetic radioactive isotopes.Silver is not radio active, none of silver's isotopes have radio activity.ur welcome!
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Both are extremely radioactive isotopes. Gold 186 has 2 more neutrons.
Today are known approx. 3 000 radioactive isotopes, natural or artificial.
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
All of them.
You might get gold but these obtained isotopes are radioactive and unstable; so it is useless.
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.
Sodium has no radioactive isotopes.
