In this science project, each coin represents an atom.M&Ms™ were shaken in a bag, poured out on the table, and then removed to the decayed pile if they did not show their “m” label.As parent element M&Ms™ were removed through radiometric decay, daughter element marshmallows replaced them.In a large collection of atoms, there is a definite time, called the half-life of the isotope, after which one-half of the total number of nuclei would have decayed.This time varies from few-millionths of a second to millions of years for different radioactive isotopes.
