What is needed to do radiometric dating

The new atom doesnt form the same kinds of chemical bonds that the old one did. It may not even be able to hold the parent atoms place in the compound it finds itself in, which results in an immediate breaking of the chemical bonds that hold the atom to the others in the mineral. In the next part of this article, Ill examine several different radiometric dating techniques, and show how the axioms I cited above translate into useful age measurements. C14 is also formed continuously from N14 (nitrogen-14) in the upper reaches of the atmosphere.

A third, very rare type of radioactive decay is called electron absorption.The mass number doesnt change, while the atomic number goes down by 1.So an atom of potassium-40 (K40), atomic number 19 can absorb an electron to become an atom of argon-40 (Ar40), atomic number 18.Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.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.
