The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay. Half-life is the amount of time it takes for half of the parent isotopes to decay. The decay occurs on a logarithmic scale. For example, the half-life of C is 5, years.go
How reliable is geologic dating?
In the first 5, years, the organism will lose half of its C isotopes. In another 5, years, the organism will lose another half of the remaining C isotopes. This process continues over time, with the organism losing half of the remaining C isotopes each 5, years. Fossils are collected along with rocks that occur from the same strata. These samples are carefully cataloged and analyzed with a mass spectrometer. The mass spectrometer is able to give information about the type and amount of isotopes found in the rock.
Scientists find the ratio of parent isotope to daughter isotope. 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. Recognition that is radiometric dating methods prove carbon content. Geological process what archaeologists agree: There are important age of once-living materials that are 3. Repeat steps 3 lessons on them.
