This whole discussion of isotopes brings us back to Dalton's Atomic Theory. Each carbon atom has the same number of protons (6), which is equal to its atomic number. If it is Carbon, its atomic number is 6. Radioactivity indicates that these nuclei are unstable and decay by emitting ionizing radiation. Total number of protons in the nucleus is called the atomic number of the atom and is given the ... Carbon-13 is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons. They all have an atomic number of 6, but differ in their atomic masses. Carbon 12.
