What isotope is used in carbon dating rules for dating someone older than you

Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.

For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons.

The number of neutrons in the nucleus can vary in any given type of atom.

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.

This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.

With our focus on one particular form of radiometric datingcarbon dating—we will see that carbon dating strongly supports a young earth.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.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.The variation is certainly partially the result of a change in the cosmic ray production rate of radiocarbon.
