Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
No, Barium has both stable and radioactive isotopes. Out of its 25 known isotopes, only 6 of them are considered radioactive. The most stable isotope of Barium is Barium-138, which is not radioactive.
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Uranium is considered a radioactive chemical element because uranium (all the isotopes) is unstable and emit nuclear radiations.
Sodium has no radioactive isotopes.
Radioactive isotopes are not stable.
All the uranium isotopes are radioactive.
All radioactive isotopes will disintegrate.
All isotopes of francium are radioactive.
Astatine, a radioactive element found in the halogen group, has at least 20 known isotopes. However, only one of these isotopes, Astatine-210, is considered stable. The other isotopes are unstable and undergo radioactive decay.
radioactive isotopes! :)
Some examples are deuterium and tritium which are radioactive isotopes of hydrogen.
There are different isotopes of strontium. While some isotopes of strontium are stable and non-radioactive (e.g., strontium-88), other isotopes are radioactive (e.g., strontium-90). Strontium-90 is considered a hazardous radioactive isotope because it can be absorbed by the body and increase the risk of cancer.
