Radioactive carbon dating half life - How accurate are Carbon-14 and other radioactive dating.


The number of protons in the nucleus of an atom determines the element. For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons. The number of neutrons in the nucleus can vary in any given type of atom. So, a carbon atom might have six neutrons, or seven, or possibly eight—but it would always have six protons. An “isotope” is any of several different forms of an element, each having different numbers of neutrons. The illustration below shows the three isotopes of carbon.

In this lesson, students explore how living things are affected by changes in the environment by studying the case of the snowshoe hare and how it’s impacted by climate change.
