No, they are not different. The Atomic Mass number is the average of the total number of the protons and neutrons in the atom of the existing isotopes of an element. That's why the atomic mass number is sometimes not a whole number but a decimal number as in oxygen being 15.999. FYI isotopes are different atoms of the same element that contain the same number of protons but have a different number of neutrons.

Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
How are the atomic mass and the atomic number different?
the atomic mass is the number of protons and neutrons in an atom of an element and the atomic number is the number of protons of an atom of an element.
Is the mass of an iron atom any different from the mass of a copper atom?
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
Why is the atomic mass of an atom the average atomic mass?
It allows for the relative abundances of different isotopes.
Is the atomic mass of an element equaled to the mass of an average atom?
The atomic weight is taken as the average weight or mass of the different isotopes of the Same atom That exists in the different %age in our enviromenT
What is the atom with same atomic number but different 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.
What has a different mass number than the normal atom?
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 of and 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.
How do you determine the atom the atomic mass of an atom?
Proton + Nuetron = Atomic Mass
How is the mass number different from the average atomic mass?
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 of an atom?
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
