These are released as radioactive particles (there are many types).This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.Carbon-14 is a method used for young (less than 50,000 year old) sedimentary rocks.This method relies on the uptake of a naturally occurring radioactive isotope of carbon, carbon-14 by all living things.

This has to do with figuring out the age of ancient things.

Each element is made up of atoms, and within each atom is a central particle called a nucleus.

Within the nucleus, we find neutrons and protons; but for now, let's just focus on the neutrons.

For example, you can’t find the remaining amount of an isotope as 7.5 half-lives by finding the midpoint between 7 and 8 half-lives.

This decay is an example of an exponential decay, shown in the figure below.

Knowing about half-lives is important because it enables you to determine when a sample of radioactive material is safe to handle.
