The average mass of an element's naturally occurring isotopes is referred to as its atomic weight, which is typically expressed in Atomic Mass units (amu). This value is calculated by taking into account the relative abundances of the element's isotopes and their respective masses. For example, the atomic weight of carbon is approximately 12.01 amu, reflecting the predominance of carbon-12 and the contributions from its other isotopes. It is important to note that atomic weights can vary slightly based on the source and the isotopic composition of the sample.
What else can I help you with?
When the masses of naturally occurring isotopes of a particular element are averaged the result is called the elements of what?
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.
Why do elements have a listed average atomic mass and not just atomic mass?
Because most naturally occurring elements are a mixture of isotopes, each having a different atomic mass. These individual isotopic atomic masses must be combined accounting for the amount of each isotope of the element is present to get a weighted average atomic mass.
What is the number determined by the average mass of naturally occurring atoms of a given element?
I believe it is a mole
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.
When the masses of all naturally occurring isotopes of a particular element are averaged the result is call the elements?
Yes!
When the masses of naturally occurring isotopes of a particular element are averaged the result is called the elements of what?
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.
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.
When the masses of all naturally occurring isotopes of a particular element are averaged the result is called the elements?
Atomic weight, if the average is taken by weighting the mass of each naturally occurring isotope by its natural abundance.
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.
Is the weight average mass of all the known isotopes for an element?

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.
What is the mass number of sliver?
Mass number is a property of isotopes, not elements themselves. Naturally occurring silver is a mixture of isotopes with mass numbers 107 and 109, with an average atomic mass of 107.9.
How do you calculate the average mass of a naturally occurring element?
By multiplying the mass number of each naturally occurring isotope of the element by the fractional abundance of the same isotope, then adding all the resulting products.
Are the mass number is an average of the masses of all naturally occurring isotopes of an element?
Yes they do.

What is a weighted average of the masses of all of the naturally occurring isotopes of an element?
The mean Atomic Mass.
