The atomic mass unit (amu) is defined as exactly one-twelfth of the mass of a carbon-12 atom. This choice was practical because carbon-12 is both stable and abundant in nature. Carbon-11 is radioactive with a short half-life of about 20 minutes, Carbon-14 is radioactive with a half-life of approximately 5,730 years (used in radiocarbon dating), and Carbon-13 is a stable isotope comprising about 1.1% of natural carbon.
