Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. This difference in neutron count results in variations in atomic mass. For instance, carbon-12 and carbon-14 are isotopes of carbon, with carbon-12 having 6 neutrons and carbon-14 having 8 neutrons.
