DOC Half-Life Radioactive Isotopes Chemistry: Half-Life of Radioactive Isotopes. Introduction: The half-life is a measure of how much time it takes for ½ of a sample of radioactive atoms to decay into stable, or non-radioactive, atoms. After one half-life passes, only ½ of the atoms are still radioactive - the other half are stable. After a second half-life passes, another ...

Half-Life in Chemistry: Calculations and Examples - PSIBERG The half-life of a substance (atoms, molecules, or ions) refers to the time it takes for half of its given amount to radioactively decay. The rate at which reactants are converted into products is always proportional to the concentration of reactants present. This study of the rate of decomposition of chemical species is called rate kinetics.
