There are several possibilities for elements that are always radioactive and are artificially produced:
Technetium
Promethium
Any element with atomic number 92 (plutonium) or heavier. There are approx 25 of these in existence up to element 118 (element 117 has not been made yet). Additionally, it could be argued that plutonium is found naturally. But only the faintest traces can be found, and could be said to be produced artificially via neutron capture by uranium. It might be (and probably is) possible to create technitium or promethium in the same manner if precursor nuclei for those elements are found with naturally occurring uranium. Neutron capture is possible across a fairly wide range of elements.

No istope of plutonium is found in nature. It is made in special reactors, then purified and separated for use in bombs. Strontium is a naturally occurring element, but some isotopes were not in nature until atomic bombs exploded. Strontium-90 is a radioactive isotpe that is a byproduct of atomic fission. All elements on the Periodic Table after uranium are synthetic radioactive elements.

Which element is radioactive and synthetic?
All transuranic elements are synthetic and radioactive.
Are synthetic elements radioactive?
Synthetic elements are usually radioactive, but not necessarily so. It is conceivable for a non-radioactive neutral atom to be produced by a nuclear spallation reaction.
Is gold radioactive?
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!
Synthetic elements comprise a majority of which of the following groups?
Artifficial radioactive elements are situated in: - period 7 - actinoids (actinides) family
Is irradiation the same as radioactive iodine?
Nearly 100% of iodine found in nature is stable, though there are traces of 129I, which is radioactive and only found in insignificant quantities. Like all elements, iodine has synthetic radioactive isotopes.

All synthetic elements are?
radioactive
What elements are radioactive and synthetic?
einsteinium,......
What are all synthetic elements?
Radioactive
What is the name of the series which contains most of the synthetic and radioactive elements?
All of the actinides are radioactive, and almost all are synthetic.
What elements is radioactive and synthetic well the answer is mendelevium?
Yes, mendelevium is man made and radioactive.
Are all transition elements are radioactive?
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.
Is boron radioactive?
There are no radioactive isotopes of boron that are ordinarily found in nature. All elements have synthetic radioactive isotopes, however.
Is neon radioactive?
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
Are synthetic elements harmful?
Yes, because they are very radioactive and toxic.
Is gold radioactive?
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!
