Half life and radioactive dating mastering physics
This has to do with figuring out the age of ancient things.If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn’t be able to predict when that particular atom might decay.If we knew the fraction of a radioactive element still remaining in a mineral, it would be a simple matter to calculate its age by the formula To determine the fraction still remaining, we must know both the amount now present and also the amount present when the mineral was formed.Contrary to creationist claims, it is possible to make that determination, as the following will explain: By way of background, all atoms of a given element have the same number of protons in the nucleus; however, the number of neutrons in the nucleus can vary.
It takes a certain amount of time for half the atoms in a sample to decay.

Immer wenn ein Lebewesen stirbt, beginnt eine Stoppuhr zu laufen.
Die Wissenschaft kann diese Uhr ablesen und so das Alter eines Fundes ermitteln. Source unknown — possibly das Museum für Vor‑ und Frühgeschichte (the Museum for pre‑ and early history) in Berlin.This decay is an example of an exponential decay, shown in the figure below.
