The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
The weighted average of the masses of all naturalisotopes of an element is called atomic weight.
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.

The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.
Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).
The relative abundance of each isotope of an element is used to determine its atomic mass. This is the weighted average of all naturally occurring isotopes.
How do you calculate percent abundance of an isotope?You find the isotope number and then you calculate that into a fraction and then turn the fraction into a percentage and divide it by the atomic number then times it by the mass and turn that answer into a percent and voila, there you have it.
the Atomic Mass
The average of all the naturally occurring isotopes of a particular element are an element's 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.

Yes they do.
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.
The mean Atomic Mass.
The atomic weight of the element (syn.: mass number).
Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).
The masses and relative abundances of all naturally occurring isotopes of the element are required to calculate average atomic mass of the element.
The radon isotopes 222Rn and 220Rn are natural isotopes.
