# C14 carbon dating formula

In this equation, the units of measure for N and No can be in grams, atoms, or moles.It does not matter as long as they are like measures.When these energetic neutrons collide with a nitrogen-14 (seven protons, seven neutrons) atom it turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).Since Nitrogen gas makes up about 78 percent of the Earth's air, by volume, a considerable amount of Carbon-14 is produced.Amateur Radio | |Biology | Books | Chemistry | Data Sheets | Electronics | Math | Microscope | NASA-TV | | Photography | Physics | Radio Astronomy | Robots | Science News | Space-Astronomy | Transistors | Search This Site | The OCR Carbon Dating Home Page Carbon Dating Carbon Dating How accurate are Carbon-14 and other radioactive dating methods?

Plants take in carbon-14 through the process of photosynthesis.The units of measure for time are dependent upon the unit of measure for the rate constant.The ratio of "N/N Carbon-14 is a radioisotope formed in our atmosphere by the bombardment of nitrogen-14 by cosmic rays., where r is a measurement of the rate of decay, k is the first order rate constant for the isotope, and N is the amount of radioisotope at the moment when the rate is measured.The rate of decay is often referred to as the activity of the isotope and is often measured in Curies (Ci), one curie = 3.700 x 10" is the initial amount of radioisotope at the beginning of the period, and "k" is the rate constant for the radioisotope being studied.
