Radiometric dating technique used to date lucy validating identify comcast
Scientists use relative dating to help determine the age of their finds.Rather than relying on tests like carbon dating (used for absolute dating), they look at the items they've found in relation to something else.
Radiometric dating is a technique used to date materials based on a knowledge of the decay rates of naturally occurring isotopes, and the current abundances.
Various methods exist differing in accuracy, cost and applicable time scale All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.
Additionally, elements may exist in different isotopes, with each isotope of an element differing only in the number of neutrons in the nucleus.
A particular isotope of a particular element is called a nuclide. That is, at some random point in time, an atom of such a nuclide will be transformed into a different nuclide by the process known as radioactive decay.
This transformation is accomplished by the emission of particles such as electrons (known as beta decay) or alpha particles.
