Neutrons that come from these fragmented atoms collide with C to be useful in age estimates.This is a critical assumption in the dating process.The illustration below shows the three isotopes of carbon.Some isotopes of certain elements are unstable; they can spontaneously change into another kind of atom in a process called “radioactive decay.” Since this process presently happens at a known measured rate, scientists attempt to use it like a “clock” to tell how long ago a rock or fossil formed.God knows just what He meant to say, and His understanding of science is infallible, whereas ours is fallible.So we should never think it necessary to modify His Word.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.

So, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons.

An “isotope” is any of several different forms of an element, each having different numbers of neutrons.

Recall that atoms are the basic building blocks of matter.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.
