Atomic Mass is the number of protons in an atom
mass number is the number of protons plus neutrons in an atom
The mass number is the sum of the number of protons and neutrons of 1 specific isotope. The atomic mass is the average mass numbers of all isotopes of that atom.
In simple terms, the atomic mass is the number of protons plus the number of neutrons. The atomic number is the number of protons.
Different isotopes of an element have the same atomic number, they (only) differ in (atomic) mass NUMBER.
Isotopes differ in the number of neutrons. All atoms are neutral - they always contain the same number of protons (positive) as electrons (negative). If they lose or gain electrons, they become ions. If they lose or gain protons (as in radioactive decay), they become a different element. An element is defined by its atomic number, which is the number of protons. Atoms may differ in their atomic mass. The difference is due to differing numbers of neutrons. The atomic mass on the periodic chart is the proportional average of all the naturally occurring isotopes. To determine how many neutrons in an atom, subtract the atomic number from the 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.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
no, the atomic number, for the most part, is how much protons and electrons there are. The number of neutrons is determined when you subtract the atomic number from the atomic mass. When chemical bonding happens however, the number of electrons and protons could differ.

Because the atomic number indicates the number of protons per nucleus while the mass number is the sum of the number of protons and the number of neutrons per nucleus, and all atoms except hydrogen-1 have neutrons in their nuclei.
They are called as isotopes in which mass number differ by emmision of radiation
If you look critically, then you can say that mass is the amount of matter contained in a body and weight is the force with which an object is pulled by earth's gravitational force.But in this case, atomic mass is the mass of an atom (expressed as a dimensionless number = the number of protons + number of neutrons), while atomic weight is a weighted average of a sample of the substance. With different isotopes, it will differ from the atomic mass. See related link.

Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
