WebCarbon-11. Carbon-11 or 11 C is a radioactive isotope of carbon that decays to boron-11.This decay mainly occurs due to positron emission, with around 0.19–0.23% of decays instead occurring by electron capture. It has a half-life of 20.3402(53) min.. 11 C → 11 B + e + ν e + 0.96 MeV 11 C + e − → 11 B + ν e + 1.98 MeV. It is produced from nitrogen in a … Elements are composed either of one nuclide (mononuclidic elements), or of more than one naturally occurring isotopes. The unstable (radioactive) isotopes are either primordial or postprimordial. Primordial isotopes were a product of stellar nucleosynthesis or another type of nucleosynthesis such as cosmic ray spallation, and have persisted down to the present because their rate of decay is so slow (e.g. uranium-238 and potassium-40). Post-primordial isotopes wer…
