WebIntroduction. As mentioned in the previous section, atoms that have the same atomic number (number of protons), but different mass numbers (number of protons and neutrons) are called isotopes (nuclides). There are naturally occurring isotopes and isotopes that are artificially produced. Webexample, the element carbon—shown as ‘C’ on the periodic table in Figure 2—has three common isotopes. All three have six protons, but each has different numbers of neutrons: one has six, one has seven, and one has eight neutrons. A useful shorthand for isotopes consists of the chemical symbol
