The Relative Atomic Mass has to take into account the abundance of each isotope - which is why the answer is generally not a whole number (integer) and why the definition contains the phrase "weighted mean". Relative Isotopic Mass is the mass of one particular isotope. ...The Relative Atom...
This chapter discusses the relative atomic masses, molecular masses, and the mole concept. The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, th...
(Chemistry) the sum of all the relative atomic masses of the atoms in a molecule; the ratio of the average mass per molecule of a specified isotopic composition of a substance to one-twelfth the mass of an atom of carbon-12. Symbol:MrAbbreviation:r.m.m.Former name:molecular weight ...

Relative Isotopic Mass- This is the ratio of the mass of a single atom to the mass of a unified atomic mass unit. This is synonymous with atomic mass. Standard Atomic Weight- This is the expected atomic weight or relative atomic mass of an element sample in the Earth's crust and atmosph...
Solar systemThis brief special communications article gives data for atomic abundances and mass fractions for the elemental and isotopic solar system composition, the atomic masses of the elements and their isotopes, the composition of the solar photosphere, and the compositions of the major chondri...
Examples of relative atomic mass relative atomic mass For the natural isotopic composition of each element it shows "name", "atomic number", "symbol", "atomic weight" (orrelativeatomicmass) and a link to the element's "isotopes". From ...
(ii) Define the term 'isotopes'.[1(iii) Calculate the percentage abundance of the fourth isotope of element X.[1](iv) Given the isotopic mass of the fourth isotopes is 53.03, draw a peak for the4th isotope on the mass spectrum shown.[1](ii) Element X has a relative atomic mass of...
The RAM is fractional, not only because of the isotopic composition, but because isotopes themselves do not usually have an exactly whole number atomic mass. This is partly because of the mass of electrons as well as nucleons, and partly due to the conversion of mass to binding energy. ...
