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.
There are two main applications for radiometric dating.
If we accept God’s testimony regarding the Flood, we cannot logically believe in millions of years.We commonly hear scientific-sounding arguments that the earth and universe are billions of years old. So we should expect to find plenty of evidence for its youth.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.Most people, including Christians, still claim dogmatically that the earth looks old.
If we look at the earth through the “glasses” of human reasoning—that only snail-paced present geological processes can explain the past—then the earth does indeed look old.Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions 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.The procedures used are not necessarily in question. The secular (evolutionary) worldview interprets the universe and world to be billions of years old. The use of carbon-14 dating is often misunderstood.Carbon-14 is mostly used to date once-living things (organic material). Carbon-14 is constantly being added to the atmosphere.The illustration below shows the three isotopes of carbon.
