Non radiometric dating techniques

Rated 4.44/5 based on 706 customer reviews

A nuclide of an element, also called an isotope of an element, is an atom of that element that has a specific number of nucleons.

Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.

After all, textbooks, media, and museums glibly present ages of millions of years as fact.Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.The rules are the same in all cases; the assumptions are different for each method.To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.
