Carbon 14 dating calculations

Thus it appears that God probably created those elements when He made the original earth.

In contrast, radiocarbon forms continually today in the earth’s upper atmosphere.

It’s assumed to be the same number of carbon-14 atoms as in elephants living today.

With time those sand grains fall to the bottom bowl, so the new number represents the carbon-14 atoms left in the mammoth skull when we found it.

Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. The most well-known of all the radiometric dating methods is radiocarbon dating.

Carbon-14 can yield dates of only “thousands of years” before it all breaks down.

Chemists have already determined how many atoms are in a given mass of each element, such as carbon.4 So if we weigh a lump of carbon, we can calculate how many carbon atoms are in it.

We can measure in the laboratory how many carbon-14 atoms are still in the skull.

If we assume that the mammoth originally had the same number of carbon- 14 atoms in its bones as living animals do today (estimated at one carbon-14 atom for every trillion carbon-12 atoms), then, because we also know the radiocarbon decay rate, we can calculate how long ago the mammoth died. This dating method is similar to the principle behind an hourglass.6 The sand grains that originally filled the top bowl represent the carbon-14 atoms in the living mammoth just before it died.

Although many people think radiocarbon dating is used to date rocks, it is limited to dating things that contain the element carbon and were once alive (like fossils).

Rb)—are not being formed on earth, as far as we know.
