... different number of neutrons). Isotopes behave the same chemically, because they are the same element. The only difference is that one is heavier than the other, because of the additional neutrons. For example, carbon-12 and carbon-14 are both isotopes of carbon. Carbon-12 has 6 neutrons; carbon ...
