All elements have radioactive isotopes. Add a couple of hundred neutrons, and any stable element becomes radioactive.
Technetium, promethium, and anything heavier than bismuth (element 83) will have radioactive decay.
radio active elements can be uranium,radium,thorium,polonium,actinium etc.usually all elements of atomic number higher than 82 show radioactivity.

hydrogen-3 (or tritium) is radioactive (or unstable)........hoped that helped.

How do you use radioactive element in a sentence?
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
Is uranium an element?
Uranium is a radioactive element; the isotope 235 is fissile with thermal neutrons; the isotope 238 is not so fissile but is fertile (transformation in the fissile isotope plutonium 239). Consequently, uranium is a good nuclear fuel and also can be used in nuclear weapons.
Has Uranium changed over time?
The chemical and physical properties of uranium remain unchanged. But because uranium is a radioactive element the quantity of uranium on the earth is permanently changed due to radioactive decay.
