There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
What else can I help you with?
Are all radioative elements synthetic?
No, some elements (Ac, Th, Pa, Rn, U, Th, etc.) and many other isotopes are natural elements or isotopes.
Isotopes of elements?
Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
Find one element on the chart that has no stable isotopes?
Technetium, Promethium, and all elements heavier then Bismuth.
Is erbium radioactive?
All erbium ordinarily found in nature is of stable isotopes. Like all other elements, erbium has synthetic radioactive isotopes.
What is the average mass of the mixture of an elements isotopes?
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
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.
All isotopes of this element are radioactive?
Radioactive Elements (38) These elements are radioactive. They either have no stable naturally occurring isotope, or else are entirely artificial (all artificial elements have no stable isotopes). by Andrew Moore
Which elements have different isotopes?
Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc
Does argon have isotopes?
yes, all elements have isotopes. some stable, some radioactive.
Are all radioative elements synthetic?
No, some elements (Ac, Th, Pa, Rn, U, Th, etc.) and many other isotopes are natural elements or isotopes.
Why are most elements radioactive?
Most of the natural occurring (isotopes of) elements are NOT radioactive.Though most of all the known isotopes are radioactive but most of them do NOT naturally occur.
Is hydrogen an radioactive?
Usually not, but all elements have radioactive isotopes.

Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
What is the weighted-average mass of all the known isotopes for an element?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
The average mass of all the known isotopes of an element is what?
