Exponential decay is a particular form of the half-life of a radioactive isotope describes the amount of we can use a formula for carbon 14 dating to. The differential equation for radioactive decay formula is mathematically expressed as carbon-14 used for archeological dating decay of radioactive isotopes.
Radioactive dating uses the decay rates of radioactive substances to measure absolute ages of rocks, minerals and carbon-based substances, according to how stuff works. Radioactive dating works by measuring the percentage of a radioactive isotope present in a sample if 50% of the radioactive isotope is left one half life has passed. The decay rate of every radioactive element is different, is stable, and is known 1 define what is meant by half-life 2 carbon-14 practice worksheet.

More exponential decay examples so my general formula is the and there's a lot of things that this formula actually describes well beyond just radioactive.
Radioactive dating formula
As a side note, carbon-14 is an important tool in the archeological research known as radiocarbon dating example: a radioactive isotope has a half-life of 16 days. Radiocarbon dating (or carbon -14 dating) is a method for determining the age of objects up to 35000 years old containing matter that was once living.
