Atomic mass is the sum of the masses of the protons, neutrons, and electrons in an atom

Grant Walker · Answer 2

Atomic mass is the sum of the masses of the protons, neutrons, and electrons in an atom, or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons.
