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.Archaeologists have long used carbon-14 dating (also known as radiocarbon dating) to estimate the age of certain objects.

Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.

The number of protons in the nucleus of an atom determines the element.

Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.

Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.

Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.
