atomic weight
A term used to represent the mean relative atomic mass of an element in nature, as distinct from the relative atomic mass of a single isotope
Former term for the more specific relative atomic mass

The equivalent weight of an element or compound is that weight equivalent in reactive power to one atomic weight of hydrogen.

The average mass of an atom of an element, usually expressed relative to the mass of carbon 12, which is assigned 12 atomic mass units. Ratio of the average mass of a chemical element's atoms to 1 12 the mass of an atom of the carbon-12 isotope. The original standard of atomic weight, established in the 19th century, was hydrogen, with a value of
From 1900 until 1961, the reference standard was oxygen, with a value of 16, and the unit of atomic mass was defined as 1 16 the mass of an oxygen atom. Oxygen, however, contains small amounts of two isotopes that are heavier than the most abundant one, and 16 is actually a weighted average of the masses of the three isotopes of oxygen. Therefore, the standard was changed to one based on carbon-12. The new scale required only minimal changes to the values that had been used for chemical atomic weights
weight of one atom of a particular element (one unit of weight is equal to 1/12 of the weight of a carbon-12 atom)
(chemistry) the ratio of the atomic mass of an element to half the atomic mass of carbon-12
