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.
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
By taking the wieghted averages of naturally occurring isotopes of that element. :)
Yes they do.
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.
Thallium is a naturally occurring element in the Earth's crust. It is not a man-made element.
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.
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 atomic weight of the element (syn.: mass number).
I believe it is a mole
