Well, the mass number of an atom is simply the number of massive, nuclear particles, protons, and neutrons....

Explanation:

And so for #""^1H#, the mass number is simply 1; for #""^2H#, the mass number is simply 2; for #""^3H#, the mass number is simply 3. The isotopes contain #"0, 1, 2 NEUTRONS"# respectively.

Most of the heavier atoms have a range of isotopes, and the quoted atomic mass on the Table is the weighted average of the isotopic masses..
