Similarly, when all the atoms of the radioactive element are gone, the rock will no longer keep time (unless it receives a new batch of radioactive atoms).The rate of loss of sand from from the top of an hourglass compared to exponential type of decay of radioactive elements.The next few pages cover a broad overview of radiometric dating techniques, show a few examples, and discuss the degree to which the various dating systems agree with each other.
In exponential decay the amount of material decreases by half during each half-life.
This paper is available on the web via the American Scientific Affiliation and related sites to promote greater understanding and wisdom on this issue, particularly within the Christian community.

Rightly Handling the Word of Truth Arguments over the age of the Earth have sometimes been divisive for people who regard the Bible as God's word.

The passage of time can be charted by the reduction in the number of parent atoms, and the increase in the number of daughter atoms.
