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 ...
"An atomic weight (relative atomic mass) of an element from a specified source is
the ratio of the average mass per atom of the element to 1/12 of the mass of ...
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 ...
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.
Atomic Weight. How did Mendeleev know the weights of different atoms? Good
question. Nineteenth century chemists couldn't take individual atoms and plunk ...
Atomic weights were formerly determined directly by chemical means; now a
mass spectrograph is usually employed. The atomic mass and relative
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.
Since atoms were far too small to be measurable in absolute terms during the 19
<sup>th</sup> century, chemists determined elemental atomic weights in relative terms.
Why do some elements have no standard atomic weight? 4. ... with more than
one isotope, their atomic weight depends on the relative amounts of the isotopes,
