the mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atomso its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24再给另一个例子...
In 1803,John Daltonsuggested a way to express relative atomic mass in terms of hydrogen-1 (protium). Subsequently,Wilhelm Ostwaldsuggested expressing the relative atomic mass as one-sixteenth the mass ofoxygen. But, when isotopes and isotopic oxygen were discovered, it created confusion about how ...

The overall mass of an atom is determined by the mass of its protons, neutrons, and electrons. How does the mass ratio using H+ and H- differ from the atomic mass of hydrogen? The mass ratio using H+ and H- only takes into account the masses of these two particles, whereas the...
The average atomic mass of oxygen is 15.999 AMU. This value rounds to 16, which indicates that oxygen-16 is the most abundant isotope of oxygen... Learn more about this topic: Average Atomic Mass | Definition, Formula & Calculation from...
