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.And since carbon is an essential element in living organisms, C14 appears in all terrestrial ( get C14 from the environment.The mass number doesnt change, while the atomic number goes down by 1.

In other words, electron absorption is the exact reverse of beta decay.

After emission, it quickly picks up two electrons to balance the two protons, and becomes an electrically neutral helium-4 (He4) atom. When an atom emits a beta particle, a neutron inside the nucleus is transformed to a proton.

The mass number doesn't change, but the atomic number goes up by 1.

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.

Some, however, are unstable -- given time, they will spontaneously undergo one of the several kinds of radioactive decay, changing in the process into another element.
