The ratio of the average mass per atom of an element to 1/12 of the mass of nuclide 12C. An atomic weight can be defined for a sample of any given isotopic composition. The standard atomic weight refers to a sample of normal terrestrial isotopic composition. The term relative atomic mass is synonymous with atomic weight.
The relative atomic mass is the number of times heavier an atom is compared to one twelth of a carbon-12 atom. The periodic table
average mass of the atoms of the isotopes of a given element as they occur naturally. The isotopes of a given element have atoms with the same number of protons but different numbers of neutrons
Relative atomic mass ( r) is the ratio of the average mass per atom of the naturally occurring form of an element to 1/12 of the mass of nuclide 12C. The term atomic weight is synonymous with relative atomic mass.
the mass of an atom, approximately equal to the sum of the number of protons (Z) and neutrons (N), e.g.,56Fe has an atomic mass of 56, made up of 26 protons plus 30 neutrons, 26+30=56
The mass of an atom relative to one atom of carbon. Carbon has a RAM of 12.
(chemistry) the ratio of the atomic mass of an element to half the atomic mass of carbon-12
The mass of an atom of that element compared with one twelfth of the mass of the carbon-12 isotope.
