More Commonly Known as Relative Atomic Mass Atomic massis used interchangeably with atomic weight, although the two terms don't mean precisely the same thing. Another issue is that "weight" implies a force exerted in a gravitational field, which would be measured in units of force, like newtons...
So, when the term atomic weight was coined back in 1808, isotopes were unknown and Earth gravity was the norm. The difference between atomic weight and atomic mass became known when F.W. Aston, the inventor of the mass spectrometer (1927) used his new device to study neon. At that time...
