From Wikipedia (see the Related Link below):
By emitting an electron and an anti-neutrino, carbon-14 is changed into stable (non-radioactive) nitrogen-14. This decay can be used to get a measure of how long ago a piece of once-living material died. However, aquatic plants obtain some of their carbon from dissolved carbonates which are likely to be very old, and thus deficient in the carbon-14 isotope, so the method is less reliable for such materials as well as for samples derived from animals with such plants in their food chain.
The reaction is:
146C ---> 147N + e- + antineutrino
Carbon-14 is a radioactive isotope of Carbon-12. It has two extra neutrons in the nucleus. It decays with Beta Minus (B-) decay with a half-live of about 5700 years. Carbon-14 is in living things in a specific ratio of Carbon-14 to Carbon-12. Scientists can date the material by comparing the percentage of Carbon-14 against the amount of Carbon-12. The reason this works is because the amounts of Carbon-12 and Carbon-14 is relatively constant while the organism is alive, and begins to decay with that 5700 year half-live at the moment of death.
Over the centuries, the amount of Carbon-14 available for the organism to ingest has varied. The results in the need to correct the decay curve of the Carbon-14.
During the beta decay the nucleus loses one neutron and gains one proton so Atomic Mass remains the same while atomic number is increases by one unit so carbon-14 is converted into Nitrogen-14.
Carbon-14 decays to produce Nitrogen-14 through a negative beta emission. In this process, a neutron in the carbon-14 emits an electron and an electron antineutrino, becoming a proton in the process. The atomic number increases because the number of protons increases. The number of nucleons stays the same, so the isotope number stays the same. A compare of the mass of nitrogen-14 with that of carbon-14 indicates a loss of the mass of an electron and an antineutrino in the process, so even though the atomic number increases, the atomic mass declines very slightly.
When carbon-14 decays, it emits a negative beta particle and becomes nitrogen-14.71
Nitrogen -14.
14C radioactively decays into 14N by releasing one beta particle.
Since one of the neutrons in the nucleus transforms into a proton, it becomes nitrogen 14.
Carbon 14 decays into Nitrogen 14 via beta decay.

Isotopes.
Carbon 12 has 6 protons and 6 neutrons. Carbon 14 has 6 protons and 8 neutrons. Carbon 12 is abundant in the environment, accounting for 98.89% of all carbon and is a stable isotope of carbon. Carbon 14 accounts for only about 1 trillionth of all of the carbon on Earth and is radioactive, with a half life of roughly 5700 years, which makes it good for use in dating fossils etc
Carbon is a non metal element. Atomic mass number of it is 12.
Group 14 in the Periodic Table of Elements
Carbon with a mass of 14 is more reactive. It is an isotope. but i don't know exactly why it is more reactive..
Statistically carbon-14 atoms decay at a constant rate.
Statistically carbon-14 atoms decay at a constant rate.
Carbon dating works by measuring the amount of radioactive carbon-14 in a sample. Carbon-14 is present in all living organisms and decays at a known rate after death. By comparing the amount of carbon-14 remaining in a sample to the amount in living organisms, scientists can determine the sample's age.
Geologists use carbon-14, an isotope of carbon, and nitrogen-14 in radiocarbon dating. Carbon-14 is absorbed by all living organisms during their lifetime, and by measuring the ratio of carbon-14 to nitrogen-14 in a sample, geologists can determine its age.
Carbon 13 is stable; it does not decay into carbon 14. Since carbon 14 has a greater mass, such a decay would be impossible.
carbon 14 is a isotop of carbon 12.
Carbon 14 is the isotope that is used for carbon dating.
The carbon family is often referred to as the "Carbon Family". Boring, but true.
The daughter isotope of carbon-14 is carbon-12. The stable form of carbon.
Carbon -14 has extra two neutrons and is radioactive.
Carbon-14 because it has 2 more neutrons.
If you're using carbon- 14 dating, you need to know: 1. what the half life of carbon-14 is, so then you can roughly work out how old it is; 2. You need a sample of something now, and work out its carbon-14 count, then you can compare it to the count rate of the old artefact; 3. the old artefacts need to be tested for its counts for minutes at the moment; 4. The mass and number of carbon atomes also needs to be known.
