SUMMARY
The discussion clarifies that the mass number of an atom, defined as the total number of protons and neutrons, is typically a whole number. However, due to the existence of isotopes, the mass number can appear as a fraction when considering atomic weight, which accounts for the relative abundance of isotopes. Participants emphasized the distinction between mass number and atomic weight, highlighting that while mass number is an integer, atomic weight can be a non-integer value due to the presence of isotopes.
