| atomic weight |
The nominal atomic weight of an isotope is given by the sum of the number of neutrons and protons in each nucleus. The exact atomic weight differs fractionally from that whole number because neutrons are slightly heavier than protons and the mass of the nucleus is also affected by the binding energy

| atomic weight |
The weighted average of the atomic masses of the different isotopes of an element. A single 12 C atom, for example, has a mass of 12 amu, but naturally occurring carbon also contains a 1.1% 13 C. The atomic weight of carbon is therefore 12.011 amu.
