Carbon-14 and Uranium-235, to name two.
Yes, oxygen has three naturally occurring isotopes: oxygen-16, oxygen-17, and oxygen-18. Oxygen-16 is the most abundant, making up about 99.76% of naturally occurring oxygen.
This isotope is 210Po, an alpha emitter with a half life of 138,376 days.
Isotopes are atoms of the same element with different numbers of neutrons, while naturally occurring elements refer to all atoms of a particular element found in nature. Isotopes have the same number of protons but different atomic masses, whereas naturally occurring elements have consistent atomic masses based on the average of all isotopes present.
Molybdenum has a total of 20 isotopes, but only seven of them are naturally occurring. The most stable isotope of molybdenum is Mo-98.
Uranium deposits may contain infinitesimal amounts of technetium isotopes.
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.
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.
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Yes, oxygen has three naturally occurring isotopes: oxygen-16, oxygen-17, and oxygen-18. Oxygen-16 is the most abundant, making up about 99.76% of naturally occurring oxygen.
Carbon has a few isotopes. The most common naturally occurring isotope of it is C12. Mass number of it is 12.
Yes, gallium does have naturally occurring isotopes. The most common stable isotopes of gallium are gallium-69 and gallium-71, with gallium-69 being more abundant at about 60% and gallium-71 about 40%.
Lithium has two natural isotopes (6Li and 7Li).
The radon isotopes 222Rn and 220Rn are natural isotopes.

Tin is an element with ten naturally occurring isotopes.
