The average Atomic Mass represents the weighted average of the masses of the isotopes of the element.
The average atomic mass represents the weighted average of the masses of all naturally occurring isotopes of an element, taking into account their abundance. The value is listed on the Periodic Table and is measured in atomic mass units (amu).
The average atomic mass of an element that occurs naturally in at least one non radioactive isotope represents the sum of the products of multiplying the actual atomic mass of each naturally occurring isotope by the fractional abundance of that particular isotope in naturally occurring sources of the element. For example, the element chlorine occurs naturally as two isotopes: one with mass number 35, an actual atomic mass of 34.968852, and an abundance fraction of 0.7577; and one with mass number 37, actual atomic mass of 36.965903, and relative abundance of 0.2423. Therefore, the average atomic mass of chlorine is [(34.968852)(0.7577) + (36.965903)(0.2423)] or 35.45, to the justified number of significant digits.

When does the atomic mass of an element represent?
The average total mass of its neutrons,protons and electrons
What symbol do scientists use to represent atomic mass unit?
Scientists use the symbol "u" to represent atomic mass unit.
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
What is often used in place of atomic weights?
Relative atomic masses are often used in place of atomic weights. They represent the weighted average of the masses of the isotopes of an element relative to the mass of a carbon-12 atom.
