WebBoth carbon-12 and carbon-13 are stable, but carbon-14 is unstable, which means that there are too many neutrons in the nucleus. Carbon-14 is also known as radiocarbon. As a result, carbon-14 decays by changing one proton into a neutron and becoming a different element, nitrogen-14 (with 7 protons and 7 neutrons in the nucleus). WebFission-track dating can date material up to about 3 million years old, whereas carbon-14 can date material to only about 75,000 years old and dendrochronology to only 12,000 years old.)
