Radiocarbon dating is frequently used to date ancient human settlements or tools. It is a stable atom that will not change its atomic mass under normal circumstances. BASIS OF RADIOCARBON DATING Radiocarbon dating compares the amount of normal carbon with the amount of radioactive carbon in a sample.Exponential Decay Formula: A = A" is the original amount of the radioactive isotope that is measured in the same units as "A." The value "t" is the time it takes to reduce the original amount of the isotope to the present amount, and "k" is the half-life of the isotope, measured in the same units as "t." The applet allows you to choose the C-14 to C-12 ratio, then calculates the age of our skull from the formula above.

The normal carbon atom has six protons and six neutrons in its nucleus, giving a total atomic mass of 12.Thus it appears that God probably created those elements when He made the original earth.We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].The proton takes an electron with it and becomes an atom of hydrogen.

To measure the amount of radiocarbon left in a artifact, scientists burn a small piece to convert it into carbon dioxide gas. What effect would the declining strength of the earth's magnetic field and a catastrophic worldwide flood have on radiocarbon dates?The radioactive carbon has six protons and eight neutrons in its nucleus, giving it a total atomic mass of 14.Every 5,730 years, approximately half of this radioactive carbon spontaneously converts itself back into nitrogen by emitting an electron from a neutron.
