Comparing figures Radioactive elements "decay" that is, change into other elements by "half lives. Remember, isotopes are variations of elements with a different number of neutrons. Using the overlapping age ranges of multiple fossils, it is possible to determine the relative age of the fossil species i. The proportion of carbon left when the remains of the organism are examined provides an indication of the time elapsed since its death. This predictability allows the relative abundances of related nuclides to be used as a clock to measure the time it takes for the parent atom to decay into the daughter atom s. Samarium—neodymium dating method[ edit ] Main article: In Fig At a certain temperature, the crystal structure has formed sufficiently to prevent diffusion of isotopes.
