The average total mass of its neutrons,protons and electrons
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
The mass number is the sum of protons and neutrons in the atomic nucleus of a chemical element.
It represents the mass number of that particular isotope.
Because the gram atomic mass of an element is the mass in grams of Avogadro's Number of atoms. To find the actual mass of a single atom, the gram atomic mass must therefore be divided by 6.022 X 1023.
You only use the average atoimc weight with isotopes correct? One of the problems on MasteringChemistry asked what is the average atoimc mass of element X and gave four isotopes. I guess I was confused because I used the formula for average atoimc weight and got it wrong. Can we do one of those in lecture?
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.

Manganese is a meta element. Atomic mass of it is 25.
atomic mass
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
The mass number is the sum of protons and neutrons in the atomic nucleus of a chemical element.
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
an element of period 6 name has hafnium having atomic no 72 and atomic mass as 178.49
It represents the mass number of that particular isotope.
