Are there any naturally occurring isotopes of technetium?
Uranium deposits may contain infinitesimal amounts of technetium isotopes.
How many naturally occurring isotopes are in technetium?
Technetium is a man made element.
How are isotopes different than naturally occurring elements?
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
How can iodine z equals 53 have a higher atomic number yet lower atomic mass than tellurium z equals 52?
Because the naturally occurring isotopes of tellurium have fewer neutrons than the naturally occurring isotopes of iodine.
Can a natural isotope be radioactive?
Yes; some of the naturally occurring isotopes of the heaviest elements are radioactive.
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.
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.
What is the mass number of most common naturally occurring isotope of carbon?
Carbon has a few isotopes. The most common naturally occurring isotope of it is C12. Mass number of it is 12.
What is the average of all the naturally occurring isotopes of a particular element?
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Is radon the element naturally occurring?
The radon isotopes 222Rn and 220Rn are natural isotopes.
What are the naturally occurring isotopes of lithium?
Lithium has two natural isotopes (6Li and 7Li).
The average mass of all the known isotopes of an element is what?
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.
Is the weight 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.
Is gallium a naturally occurring isotopes?
No. Gallium is an element. The element Gallium has two naturally occuring stable isotopes (69Ga and 71Ga) and abpout 29 unstable isotopes.
Which isotopes of hydrogen has more mass percentage?
In naturally occurring hydrogen, most of the mass is that of the hydrogen-1 isotope.
Is tin an isotope?
Tin is an element with ten naturally occurring isotopes.
Are there any naturally occurring isotopes of technetium?
Uranium deposits may contain infinitesimal amounts of technetium isotopes.
