The atomic mass of an element is a weighted average of the mass of the isotopes of the element. Atomic mass is measured in atomic mass units (amu), which is based on the mass of a carbon-12 atom. The atomic mass of an element usually is close to the mass of its most abundant isotope. 50 Name Class Date

What is the atomic mass of an element? - A Plus Topper
B) The average mass of the individual isotopes of an element considering the natural abundance of each is the relative atomic mass of that element. C) The relative atomic mass of carbon is 12.01 amu because carbon-12 is the most abundant isotope, with smaller amounts of carbon-13 and carbon-14.

atomic mass, A – The number of protons plus the number of neutrons in an atom. isotopes – Atoms of the same atomic number that have different numbers of neutrons. atomic weight – This is not a weight! It is the weighted average of the atomic masses for all isotopes of an element. This is why the atomic weight of carbon is 12.011 and not ...
