Role of radioactive elements in dating events and artifacts
When we talk about an alpha particle, we use the first letter of the Greek alphabet, which is here.
After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.In fact, you might like this term better, because the dating method relies on the known decay rate of radioactive isotopes.Regardless of which name you prefer, the discovery was a true breakthrough that provided a tool to predict the geological history of the Earth and even the age of the Earth itself.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.
Plus, get practice tests, quizzes, and personalized coaching to help you succeed. So we have to rely on something called radiometric dating to figure out the age of rock.
This transformation into a different nuclide can be accomplished in different ways.
