How long does carbon dating take

When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).Carbon-14 is radioactive, with a half-life of about 5,700 years.(The periodic table of the elements also reflects the existence of isotopes by showing a weighted average for the atomic weight of each element, but I digress.) The first two isotopes, 12 C and 13 C, are stable, but 14 C is unstable; that is, it's radioactive! In other words, the amount of 14 C in dead organic matter will grow smaller.And since scientists know exactly how long an amount of 14 C takes to decay, they can compare the amount of 14 C in a specimen to the amount of 14 C a modern piece of organic matter and calculate the age of the specimen.And say that every 5,568 years you add another gallon of water to the mixture.

It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms.Radiocarbon Dating All organic matter contains carbon, which is an element.But there are different types of carbon, called isotopes.For more information on cosmic rays and half-life, as well as the process of radioactive decay, see How Nuclear Radiation Works.­The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.

The number of neutrons in the nucleus can vary in any given type of atom.
