Web122 rijen · A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z ). [1] 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.
