Each radioactive element has a unique rate of decay, called its half-life. Half-life is the average Problem: Can we use M&Ms to model radioactive dating? . 7. Using radioactive carbon (carbon dating) can also be used to date fossils. How?
A brief account of radioactivity half-life, with some worked examples. The best way to understand half-life is to try this for yourself by printing the graph and using For carbon-14 ten half-lives is only 57 300 years, so carbon dating cannot be
