Actimium, plutonium, radon, radium, thorium, uranium
Almost every substance is radioactive in your virtual lab.
All of the chemical substances from the Mendeleev Periodic Table are radioactive. That's why it is a specific table or radioactive elements and they are listed.
A radioactive element is unstable and is transformed by natural radioactive decay in other element..
As radioactive element is an element that is on the Priodic Table of Elements. A Radioactive Element is usually radioactive.
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.
No, it is not radioactive.
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Francium (Fr) is a natural radioactive element, extremely rare.
Of course. Chemistry still applies, and that is based on the electron configuration, not the nucleus, per se.
As radioactive element is an element that is on the Priodic Table of Elements. A Radioactive Element is usually radioactive.
non radioactive element
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.
The chemistry of radioactive elements and their compounds.LyN
No, it is not radioactive.
radioactive decay
No good, no bad facts; francium is a very rare chemical element, also very unstable. The chemistry of francium is largely unknown. But is a radioactive element and the radioactivity is frequently dangerous.
The radioactive element is composed of unstable nuclei that try to reach stability through emitting nuclear radiations as alpha, beta, and gamma nuclear radiations.
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Probably uranium is the best known radioactive element.
Francium (Fr) is a natural radioactive element, extremely rare.
