Isotopes are atoms of the same element (that is, with the same number of protons in their atomic nucleus), but having different numbers of neutrons. Most (66 of 94) naturally occurring elements have more than one stable isotope.Thus, for example, there are three main isotopes of carbon.or example, all carbon atoms contain 6 protons in their atomic nucleus; so the atomic number of carbon is 6.
