WebCarbon-12 has a mass of 12 amu by definition. Theoretically, this would mean that each proton and each neutron has a mass of one amu, but this turns out not to be so. The actual mass of a proton is about 1.007 amu, and the mass of a neutron is about 1.008 amu. If you add the masses of six protons and six neutrons, you get 12.09. WebUnderstanding Isotopes A = N + Z Calculations You already know how to find the mass number of an isotope by adding the protons and neutrons. We can state the relationship between protons, neutrons, and mass number with the following equation: A = N + Z atomic mass number = number of neutrons + atomic number (number of protons)
