Relate radioactive dating techniques to isotopes

The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.However, not all fossils or remains contain such elements.This chain eventually ends with the formation of a stable, nonradioactive daughter nuclide.

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

Relative dating by biostratigraphy is the preferred method in paleontology, and is in some respects more accurate (Stanley, 167–69).

The Law of Superposition was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century. Radioactive dating is more precise, not necessarily more accurate.

A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will spontaneously transform into a different nuclide.

This transformation may be accomplished in a number of different ways, including radioactive decay, either by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous fission, and electron capture.

Prior to the discovery of radiometric dating which provided a means of absolute dating in the early 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques to determine the geological events.

Though relative dating can only determine the sequential order in which a series of events occurred, not when they occur, it remains a useful technique especially in materials lacking radioactive isotopes.

Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations.

These remains are subjected to dating techniques in order to predict their ages and trace their history.

Radiometric dating is also used to date archaeological materials, including ancient artifacts.
