Atomic Structure * Learning Outcomes
... The location, charge, and atomic mass of sub-atomic particles are how they are distinguished. These masses and charges are so small (e.g. mass of proton = 0.000 000 000 000 000 000 000 000 001 67 kg), that we use new units more suitable. For mass, we use atomic mass units (u) and for charge, ...
