Chemistry of carbon dating

The rate of decrease is predictable and can be described with some accuracy, increasing our ability to perhaps date the biological events of our planet.Carbon 14 is produced in the upper atmosphere when cosmic radiation from space interacts with nitrogen gas, converting nitrogen 14 to carbon 14.

Radiocarbon dating works by comparing the three different isotopes of carbon.When the animal dies, however, uptake of carbon stops.As a result, radioactive carbon atoms are not replaced as they decay, and the amount of this material decreases over time.These carbon 14 atoms combine with oxygen to form carbon dioxide gas, which is absorbed by plants.We don’t actually know for sure if the rate of carbon dioxide formation has stayed constant over time, however, It’s usually quoted as a “small part of less than 1%” The difference casts doubt on the accuracy of the method.In 2008 we could only calibrate radiocarbon dates until 26,000 years.Now the curve extends (tentatively) to 50,000 years.Radioactive decay can be used as a “clock” because it is unaffected by physical (e.g. For instance, the amount varies according to how many cosmic rays reach Earth.This is affected by solar activity and the earth’s magnetic field.In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.This is particularly important for very old samples.


  1. Unaware of the many fallacious assumptions used in the dating process, many people believe Carbon-14 dating disproves the biblical

  2. Learn more about Chemistry Electronics, Biology, Microscopy Microscope, Amateur Radio, Photography, Radio Astronomy, Science, Home Learning and much more. www.

  3. Carbon is such an important element that an entirely separate field of chemistry is devoted to this element and its compounds. Organic chemistry is the study of carbon

  4. Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element

  5. Carbon from Latin carbo "coal" is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.
