Third, it is found not informative to leave empty spaces instead of approximate atomic weights for elements with unstable isotopes. Fourth, the term atomic weight vs the term atomic mass is discussed shortly, in agreement with the SI system of units and in contrary to the questionable IUPAC ...

Atomic Mass of First 30 Elements - Atomic Mass of Elements is Measured with the Help of its Unit - Atomic Mass Unit. One such Unit is Equal to One-Twelfth of the Mass of a Carbon-12 Atom Which is at Rest. Learn about Atomic Mass of First 30 Elements at B
If the atomic mass of hydrogen is taken as 1, the relative atomic mass of oxygen is 16. Initially, scientists obtained the atomic masses of all the elements by comparing with the mass of hydrogen taken as 1. However, the problem was that the atomic masses of most of the elements came ...
This gave a different set of relative masses for the elements. The inadequacy of oxygen as an arbitary standard led to the selection of the carbon-12 isotope of carbon as the arbitary standard. The relative atomic mass of an element is defined as the weight in grams of the number of ...
