Atomic weight is the averagemassofatomsof anelement, calculated using the relative abundance ofisotopesin a naturally-occurring element. It is the weighted average of the masses of naturally-occurring isotopes. What Is It Based On? Prior to 1961, a unit of atomic weight was based on 1/16th ...

Atomic Mass vs. Mass Number: Unravel the Mystery By Todd Helmenstine Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes. The atomic weight can change because it depends on our understanding of how much of each isotope of an...
Atomic mass is the average weighted mass number of all isotopes of a given element. It is calculated based on the frequency of different isotopes of that element. Atomic number is the number of protons in an atom's nucleus. It is the same for all atoms of a given element. What is the...
What is difference between mass number and atomic mass? Atomic mass is the weighted average mass of an atom of an element based on the relative naturalabundanceof that element's isotopes. The mass number is a count of the total number of protons and neutrons in an atom's nucleus. ...

What is the average atomic mass of an atom? Average atomic mass is a measurement that describes the average mass of individual atoms in a given element. Elements can be made of isotopes which are atoms that differ in their numbers of neutrons, and therefore differ in their atomic mass. The...
