Best Answer

Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered.

I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.

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.
