Radioactive
Some synthetic elements are naturally radioactive due to their unstable atomic structures. For example, elements beyond uranium on the periodic table are typically artificially produced and tend to be radioactive. These elements can emit radiation as they undergo radioactive decay.
All of the actinides are radioactive, and almost all are synthetic.
Yes, mendelevium is man made and radioactive.
Plutonium is a synthetic element that is radioactive. It does not occur naturally in nature and must be artificially produced through the nuclear fission of uranium.
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.
Yes, because they are very radioactive and toxic.
Curium {Note correct spelling} is only element in the list given that is radioactive and synthetic.^ not correct answer and not even spelled right the correct answer is "lawrencium"The rare earth elements are located at the bottom of the periodic table and are comprised of the lanthanoid series and the actinoid series.The actinoid series is the second row of rare earth elements. All of these elements are radioactive, and all of these elements (except actinium, thorium, protactinium, and uranium) are synthetic.
Yes, because they are radioactive.
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.
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
No isotope of silver ordinarily found in nature is radioactive. Like all elements, silver has synthetic radioactive isotopes.Silver is not radio active, none of silver's isotopes have radio activity.ur welcome!
