Atomic Weight in Chemistry. by Ron Kurtus (revised 30 August 2012). The atomic
weight—or more correctly stated: relative atomic mass—of an element is a ...
The atomic weight of an element is the relative atomic mass of that element. It is
actually a weighted mass of the elements isotopes (if any) and their relative ...
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. American Heritage®
Hydrogen, the lightest element, was assigned a relative mass of '1', and the other
elements were assigned 'atomic masses' relative to this value for hydrogen.
By postulating that simple compounds always contain one atom of each element
present, he assigned relative atomic weights to many elements, assigning a ...
Atomic Weight. How did Mendeleev know the weights of different atoms? Good
question. Nineteenth century chemists couldn't take individual atoms and plunk ...
For example, for natural Earthly carbon, which is mostly C-12 but has some C-13
also (about 1%), the relative atomic mass (atomic weight) of a carbon sample ...
Atomic weight definition, the average weight of an atom of an element, formerly
based on the weight of one ... the former name for relative atomic mass at wt.
Rather, the mass of an atom is compared with that of an atom of carbon-12. The
relative atomic mass of carbon-12 is taken to be 12. Relative masses have no ...
