This value is the atomic weight.
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
The atomic mass of an element is the weighted average of masses of the isotopes of the element, weighted in proportion to their abundance.
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
Isotopes are atoms of the same element with different numbers of neutrons, while naturally occurring elements refer to all atoms of a particular element found in nature. Isotopes have the same number of protons but different atomic masses, whereas naturally occurring elements have consistent atomic masses based on the average of all isotopes present.
They are called isotopes. They have different mass nmbers because they have a different number of neutrons.

Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
One can find an abundance of isotopes with atomic mass by conducting experiments in laboratories and analyzing the results using techniques such as mass spectrometry. Isotopes are variants of elements with different numbers of neutrons in their nuclei, leading to different atomic masses. By studying the distribution of isotopes in a sample, scientists can determine the relative abundance of each isotope present.
An atom or element that have different masses are known as isotopes.
This is the atomic weight.
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.
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.
