the carbon-12 isotope has mass number 12; neutrons = mass number - atomic number = 12 - 6 = 6, iupac periodic table of elements (carbon, atomic number 6) combined with the definition of carbon-12 (mass number 12): neutrons = mass number - atomic number = 12 - 6 = 6, iupac periodic table of the elements / nist atomic weights and isotopic compositions: carbon-12 has atomic number 6 (protons) and mass number 12, so neutrons = 12 - 6 = 6, iupac/ciaaw standard atomic weights and isotopic composition of carbon (carbon-12 defined as exactly 12 u, 6 protons, mass number 12), iupac/ciaaw standard atomic weights and isotopic compositions;

neutrons = mass number - atomic number = 6, iupac/codata definition: carbon-12 has atomic number (protons) 6 and mass number 12, so neutrons = 12 - 6 = 6 (standard nuclear physics fact, e.g. nist/iupac periodic table data), iupac/codata definition: carbon-12 has atomic number z=6 (protons) and mass number a=12; neutrons n = a - z = 6. this is the reference isotope defining the atomic mass unit (12 g/mol exactly by definition prior to 2019 si redefinition, and ar(12c) = 12 exactly by definition of the dalton)., iupac/codata nuclear data: carbon-12 has atomic number (protons) z=6 and mass number a=12, so neutron count n=a-z=6. this is a fixed physical constant, independent of blockchain state; the pinned block window is copied from the request for reference only., iupac/codata nuclide data: carbon-12 has mass number a=12 and atomic number z=6, so neutron count n = a - z = 6, iupac/codata periodic table data: carbon-12 has atomic number (protons) 6 and mass number 12, giving 12 - 6 = 6 neutrons, iupac/codata standard nuclear data: carbon-12 has 6 protons and a mass number of 12, so neutrons = 12 - 6 = 6, iupac/codata standard nuclear data: carbon-12 has 6 protons and mass number 12, giving 12 - 6 = 6 neutrons (e.g. nist atomic weights and isotopic compositions, https://www.nist.gov/pml/atomic-weights-and-isotopic-compositions-relative-atomic-masses), iupac/codata standard nuclear data: carbon-12 has atomic number (protons) 6 and mass number 12, giving 12 - 6 = 6 neutrons, iupac/codata standard nuclear data: carbon-12 has atomic number (protons) 6 and mass number 12, so neutrons = 12 - 6 = 6, iupac/codata standard nuclear data: carbon-12 has atomic number (protons) 6 and mass number 12, so neutrons = 12 - 6 = 6 (e.g. nist atomic weights and isotopic compositions database)., iupac/codata standard nuclear data: carbon-12 has atomic number (z) 6 and mass number (a) 12, so neutron count n = a - z = 6, iupac/codata standard nuclear data: carbon-12 has atomic number z=6 (protons) and mass number a=12;
