How many isotopes of elements x exist?
Different elements have between 0 and 10 naturally occurring isotopes, and between about 3 and 25 if you also include artificially prepared and characterized ones.
Can a natural isotope be radioactive?
Yes; some of the naturally occurring isotopes of the heaviest elements are radioactive.
When the masses of all naturally occurring isotopes of a particular element are averaged the result is call the elements?
Yes!
Can you find all naturally occurring compounds on a periodic table?
Periodic table lists elements and not compounds. Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally.
How many naturally occurring atoms exist?
well buddy there are only 92 elements in the periodic table occurring naturally on earth.. the rest are all man made...
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.
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

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.
Can a natural isotope be radioactive?
Yes; some of the naturally occurring isotopes of the heaviest elements are radioactive.
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.
When the masses of all naturally occurring isotopes of a particular element are averaged the result is call the elements?
Yes!
How has the amount of earths radioactive isotope changed over time?
Many elements have naturally occurring isotopes, varieties of the element that have different numbers of neutrons in the nucleus.
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.

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.
