Carbon (6C) has 15 known isotopes, from C to C , of which C and C are stable. The longest-lived radioisotope is C , with a half-life of 5.70(3)×10 years. This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reaction N + n → C + H . The most stable … See more 1. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits. 2. ^ Modes of decay: 3. ^ Bold symbol as daughter – Daughter product is stable. See more C and C are measured as the isotope ratio δ C in benthic foraminifera and used as a proxy for nutrient cycling and the temperature dependent air–sea exchange of CO2 (ventilation). Plants find it easier to use the lighter isotopes ( C ) when they convert sunlight and … See more • Cosmogenic isotopes • Environmental isotopes • Isotopic signature • Radiocarbon dating See more Carbon-11 or 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 See more There are three naturally occurring isotopes of carbon: 12, 13, and 14. C and C are stable, occurring in a natural proportion of approximately 93:1. C is produced by thermal neutrons … See more The quantities of the different isotopes can be measured by mass spectrometry and compared to a standard; the result (e.g. the delta of the C = δ C ) is expressed as parts per … See more
