ATOMIC WEIGHT VERSUS ATOMIC MASS.A letter to the editor is presented in response to the report "Atomic Weights of the Elements 2009," published in the December 20, 2010 issue.CarrollHarvey F.Chemical & Engineering News
Based on the abundance of isotopes, atomic weight is the average of the mass of all the atoms in an element. The atomic mass unit, which is 1/12th the mass of a carbon-12 atom, helps calculate atomic mass and atomic weight. Mass Defect Mass Defect is the difference between the mass...
The atomic mass of an atom is the mass of that atom compared to some standard, such as the mass of a particular type of carbon atom. The terms atomic mass and atomic weight are often used interchangeably, although, strictly speaking, they do not mean the same thing. Mass is a measure ...
atomic mass- (chemistry) the mass of an atom of a chemical element expressed in atomic mass units atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an ...
I have a little confusion regarding the terms atomic mass and atomic weight. They seem to be used interchangeably and different periodic tables use different terms. I checked around a dozen of periodic table online and they seem to use either atomic mass, atomic weight or relative atomic mass....
