Natural germanium has only one radioactive isotope - germanium 76.
27 artificial radioisotopes of germanium are known.
92.66% of the germanium found in nature is not radioactive. 7.44% of germanium is 76Ge, which has a very long half life of 1.78 x 1021 years.
Yes, germanium does form isotopes. It has five stable isotopes: germanium-70, germanium-72, germanium-73, germanium-74, and germanium-76. Additionally, there are several unstable isotopes of germanium that have been produced in laboratories.
Germanium has 9 isotopes.
No, there are many stable isotopes.
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.
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.
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.
