Introduction
The atomic mass (ma) is the mass of an atomic particle, sub-atomic particle, or molecule, most often expressed in unified atomic mass units, which by International agreement is 1/12 mass of a single carbon-12 atom at rest.

What you learn in Theory:
The nucleus is the very dense region consisting of protons and neutrons at the center of an atom.
What you learn in Practice:
The atomic mass of atomic particles is slightly less than the total mass of its constituting protons, neutrons, or electrons due to binding energy mass loss (as per E=mc2).
