Radiometric dating isotopes

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. It is our principal source of information about the age of the Earth and a significant source of information about rates of evolutionary change. 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. Some nuclides are inherently unstable.

Radiometric Age Dating - Geology (U.S. National Park Service)

If you want to know how old someone or something is, you can generally rely on some combination of simply asking questions or Googling to arrive at an accurate answer. This applies to everything from the age of a classmate to the number of years the United States has existed as a sovereign nation and counting as of But what about the ages of objects of antiquity, from a newly discovered fossil to the very age of the Earth itself? Sure, you can scour the Internet and learn rather quickly that the scientific consensus pins the age of of the planet at about 4. But Google didn't invent this number; instead, human ingenuity and applied physics have provided it. Specifically, a process called radiometric dating allows scientists to determine the ages of objects, including the ages of rocks, ranging from thousands of years old to billions of years old to a marvelous degree of accuracy.

Refuting “Radiometric Dating Methods Makes Untenable Assumptions!”

Uranium—uranium dating is a radiometric dating technique which compares two isotopes of uranium U in a sample: uranium U and uranium U. It is one of several radiometric dating techniques exploiting the uranium radioactive decay series , in which U undergoes 14 alpha and beta decay events on the way to the stable isotope Pb. Other dating techniques using this decay series include uranium—thorium dating and uranium—lead dating. This decays with a half-life of 6. This isotope has a half-life of about , years.
