Probably not, no.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
Polonium has 33 isotopes, more than any other element, of which all are radioactive.
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Sodium has no radioactive isotopes.
Radioactive isotopes are not stable.
Isotopes are just the different possible nuclear weights of each element. Some are stable; some are unstable and radioactive. Since all atoms are isotopes and all isotopes are atoms, Isotopes can - and do - form ions, consequently they can have positive and negative charges.
All the uranium isotopes are radioactive.
All radioactive isotopes will disintegrate.
All isotopes of francium are radioactive.
Isotopes with unstable nuclei are radioactive and can undergo radioactive decay to achieve a more stable state. This decay process involves the release of radiation such as alpha or beta particles. The unstable isotopes are often used in various applications, including medicine and energy production.
radioactive isotopes! :)
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
