But, for a large number of atoms, the number that will decay within a given time can be predicted.
The original (parent) atom changes into a daughter atom having different chemical properties.
(For a brief science review, see sidebar and figure 1.) The timepiece that allows dating is the “radioactive” decay of certain kinds of atoms from one form into another.
Radioactive decay results from unstable combinations of protons and neutrons in the atom’s nucleus.
But last Sunday, her Bible teacher stated emphatically that God made Earth only six thousand years ago. The age assigned to the fossils in front of her seems to contradict the creation account, and Janet’s heartbeats accelerate at the implication. Credible answers to common misconceptions about radiometric dating and a proper understanding of Scripture can help people like Janet reconcile creation accounts regarding the age of Earth.
Wiens Bewildered, Janet watches her son gaze in awe at the dinosaur exhibit. Yet, many people challenge the accuracy of radiometric dating, and misinformation describing the various radiometric techniques abounds.
Though most atoms contain stable nuclei and do not decay, some types do.
When radioactive decay occurs, no one can predict which individual atoms will decay when.
Radiometric dating can be compared to an hourglass.
When the timepiece is turned over, sand grains fall from the top of the hourglass to the bottom.
However, one significant difference exists between radiometric dating and the hourglass design.
