Carbon-12, carbon-13, and carbon-14 are isotopes of carbon, meaning they all have the same number of protons (6) but different numbers of neutrons. The isotopes differ in their atomic mass due to the varying number of neutrons, with carbon-12 having 6 neutrons, carbon-13 having 7 neutrons, and carbon-14 having 8 neutrons.
