This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.
This radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate.
The atoms of some chemical elements have different forms, called isotopes.
These break down over time in a process scientists call radioactive decay.
