Atomic Number of Carbon. However, the number of neutrons varies from six to eight. De très nombreux exemples de phrases traduites contenant "atomic mass" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. answer! Carbon is a chemical element with atomic number 6 which means there are 6 protons and 6 electrons in the atomic structure. Carbon-14 (14 C), or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. In that 12 this number is really called the average atomic mass. What factors affecting academic performance? Lv 4.
