WebFrom the periodic table, we see that the atomic number (number of protons) for the element carbon is 6. The name carbon-14 tells us that this isotope's mass number is 14. The chemical symbol for carbon is C. Now write the isotopic notation for carbon-14. 14 6 C We can determine the number of neutrons as 14 −6 = 8 neutrons. Example 2. Web1 nov. 2016 · If it is an iron isotope, then it has 26 protons, period. The iron atom is characterized by an atomic number, "Z=26. That is every iron nucleus contains 26 protons, 26, massive, positively charged, nuclear particles, by definition. Of course, the nucleus also contains 28 neutrons, 28 neutral, massive nuclear particles, to give the …
