WebOct 28, 2024 · An isotope is a variation of an element based upon the number of neutrons. The disintegration of the neutrons within the atom of the element's nucleus is what scientists call radioactivity . WebNov 8, 2016 · The definition is: The time required for one-half of the radioactive (parent) isotopes in a sample to decay to radiogenic (daughter) isotopes. --modified from Webster's Third International Dictionary, Unabridged. In other words, it is the lifetime of half the radioactive isotopes in a system.

Webin historical geology, the scientist does not have the opportunity to experiment in time but must use observation to define and test hypotheses. these lead to the method of multiple working hypotheses. the emphasis is less on the predicting the outcome of an experiment and more on the preponderance of the observed evidence. in turn, this often requires … WebIn physical terms, the closure temperature is the temperature at which a system has cooled so that there is no longer any significant diffusion of the parent or daughter isotopes out …
