Radiometric dating - Wikipedia Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

Isotopes: Principles and Applications: Gunter Faure. The leading textbook and professional resource on isotopegeochemistry–completely updated and expanded. Since its initial publication as Principles of Isotope Geologyin 1977, this has been the most widely used comprehensive textbookin upper-level isotope geochemistry courses.

Carbon-14, Radiometric Dating - CSI Carbon dating is used to determine the age of biological artifacts up to 50,000 years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

Unreliability of Radiometric Dating and Old Age of the Earth How radiometric dating works in general : Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is called the daughter element.

Introduction to Geology - Geology Cafe.com Chemical Bonds Molecular compounds are held together on an atomic level by chemical bonds. Three types of chemical bonds include ionic bonds, metallic bonds, and covalent bonds.The types of chemical bond influence the physical properties of the molecular compounds they form.
