The discussion revolves around the possibility of using another atom as the standard for the atomic mass unit (amu), currently defined by the carbon-12 atom. Participants explore the implications and methods of changing the standard, as well as historical context regarding previous standards.
Participants express differing views on the feasibility and implications of changing the standard atom for amu. While some propose alternatives, others highlight the historical context and practical considerations, indicating that the discussion remains unresolved.
The discussion includes assumptions about the availability and properties of alternative atoms, as well as the historical context of the atomic mass unit, which may not be fully explored or agreed upon by all participants.
Tonia said:Is there a reason you used four zeros?
Another atom has been used, before the standard was changed to carbon-12. This atom was oxygen, or more specifically, oxygen-16.Tonia said:The atom that is used as the standard for the atomic mass scale is the Carbon atom with an atomic number of 6 and a mass number of 12 and this carbon atom is equal to 12 unified atomic mass units. Could another atom be used as the standard, and if so, how would this be accomplished??
