The radioactivity corresponds to the neutron/proton ratio in the atom: The neutron/proton ratio for a certain element must fall within a certain range for the element to be stable.That’s why some isotopes of an element are stable and others are radioactive.The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an "isochron") by means of standard linear regression methods of statistics.And the Bible mentions lead in a number of passages.
Lead is one of only a few elements known to ancient peoples.
So, we have a “clock” which starts ticking the moment something dies.
Obviously, this works only for things which were once living.
C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.
People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.
All elements with 84 or more protons are unstable; they eventually undergo decay.
