Radiodating isotopes

Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.Radiocarbon dating works by comparing the three different isotopes of carbon.This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay.

The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.

To be able to do this lesson and understand the idea of half-life, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.

The total mass of the isotope is indicated by the numerical superscript.

While the lighter isotopes C has decayed that what remains can no longer be measured. In 5,730 years half of the C in the atmosphere, and therefore in plants and animals, has not always been constant.

With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.

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

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