Isotope
Atoms of the same element with different numbers of neutrons and different masses but the same number of protons (atomic number).
1 of 10
Relative Atomic Mass
The weighted mean mass of an atom of an element compared to 1/12th the mass of an atom of carbon-12.
2 of 10
Relative Isotopic Mass
The mass of an atom of an isotope compared to 1/12th the mass of an atom of carbon-12.
3 of 10
Relative Molecular/Formula Mass
The average mass of a molecule or a formula unit, compared to 1/12th the mass of an atom of carbon-12.
