An isotope is an element that has the same number of protons. Life is the amount of time it takes for one half of the initial amount of the parent, radioactive isotope. This method relies on the uptake of a naturally occurring radioactive isotope.

Most elements have the same number of protons and neutrons.

U-235 decays to Pb-207 with a half-life of 704 million years.

The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. In the first 5,730 years, the organism will lose half of its C-14 isotopes.

Isotope dating geology learn about geology with articles and video at How Stuff Works. Radioactive decay processes have proven particularly useful in radioactive dating for geologic processes. This module introduces the student to theoretical and practical aspects of radiometric geochronology and stable isotope geology. Teaching the fundamentals of relative dating of rocks and.

If you understand how to get to the point where you can use the dating. The study of the relative abundances of radioactive and stable isotopes in rocks to determine radiometric ages and conditions of formation. Radiometric dating Adapted from The Age of the Earth, by the Branch of Isotope Geology, United States. The Age of the Earth How do we know the Age of the.

By comparing this ratio to the half-life logarithmic scale of the parent isotope, they are able to find the age of the rock or fossil in question.

There are several common radioactive isotopes that are used for dating rocks, artifacts and fossils. U-235 is found in many igneous rocks, soil and sediment.

The mass spectrometer is able to give information about the type and amount of isotopes found in the rock.
