An example of isotopes is carbon, which has three main isotopes, carbon-12, carbon-13 and carbon-14.
All three isotopes have the same atomic number of 6, but have different numbers of neutrons.
By looking at the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing.
Radiocarbon dates do not tell archaeologists exactly how old an artifact is, but they can date the sample within a few hundred years of the age.
If two nuclei have different masses, but the same atomic number, those nuclei are considered to be isotopes.
The carbon-14 decays, with its half-life of 5,730 years, while the amount of carbon-12 remains constant in the sample.Students use M&M’s (or pennies and puzzle pieces) to demonstrate the idea of radioactive decay.This experiment is best used by student working in pairs.You might suggest that the students experiment with their graphing results to see if trends begin to form.Sign up for Re Actions™, the e-newsletter for educators that offers teaching ideas about nuclear science and technology.

The radioactive dating relies on spontaneous decomposition into other element. Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains.
