Usually not, but all elements have radioactive isotopes.
All radioactive isotopes will disintegrate.
Barium has seven isotopes, with atomic masses ranging from 130 to 138. The most abundant isotope of barium is Barium-138, making up about 71% of naturally occurring barium. Barium-137 is a radioactive isotope with a half-life of about 2.5 minutes.
All the isotopes of uranium are radioactive and unstable.
All the isotopes of americium are radioactive and unstable.
All of them.
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.
All the uranium isotopes are radioactive.
All radioactive isotopes will disintegrate.
All isotopes of francium are radioactive.
Barium has seven isotopes, with atomic masses ranging from 130 to 138. The most abundant isotope of barium is Barium-138, making up about 71% of naturally occurring barium. Barium-137 is a radioactive isotope with a half-life of about 2.5 minutes.
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.
No, there are many stable isotopes.
Plutonium and xenon are radioactive elements. Plutonium is a synthetic element, while xenon occurs naturally but can also be produced synthetically. Barium and cesium are not synthetic elements but can have radioactive isotopes.
All the actinides isotopes are radioactive; and the majority are artificial isotopes.
All the isotopes of uranium are radioactive and unstable.
Usually not, but all elements have radioactive isotopes.
All the isotopes of americium are radioactive and unstable.
