The Atomic Mass is the mass of an atom of that element in AMUs. (Atomic Mass Units)
The atomic number, however, is equivalent to the number of protons in an atom of that element.
The relative atomic mass of an element is the weighted average of the masses of the isotopes relative to 1/12 of the mass of a carbon-12 atom.
It is a weighted average as it takes into account the relative abundances of the different isotopes (atoms of the same element but with different numbers of neutrons) of an element. This number is found in the Periodic Table.
For example chlorine has two isotopes, 35Cl and 37Cl, in the approximate ratio of 3 atoms of 35Cl to 1 atom of 37Cl.
The number of protons and neutrons in a 35Cl atom must add up to 35, the mass number. The relative atomic mass of chlorine takes into account both isotopes and is therefore 35.5.

What is the definition of 'Atomic Mass'?
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.
What can the atomic mass tell you about an atom?
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.
What is the relationship btw atomic mass and atomic mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic mass number of iodine?
The atomic mass number of iodine is 17.8923
What is the number of atomic mass?
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)
What is a mass number atomic mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The Atomic Mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
What is an atomic number and a mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The atomic mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
How do you get the mass number by adding neutrons and the atomic number?
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. The atomic number represents the number of protons in an atom, so adding the atomic number to the number of neutrons will give you the mass number.
What comprises the atomic mass?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. It is approximately equal to the mass number of the atom, which is the total number of protons and neutrons. The atomic mass is typically expressed in atomic mass units (amu).
