  • Radioactive decay
    A process where unstable atomic nuclei lose energy by emitting radiation, following a first order mechanistic step.
  • First order process
    A reaction where the rate is directly proportional to the concentration of one reactant.
  • Decay constant
    A first order rate constant denoted by k, specific to radioactive decay processes.
  • Integrated rate law
    An equation that relates the concentration of reactants to time, used to determine reaction kinetics.
  • Reaction order
    The power to which the concentration of a reactant is raised in the rate law.
  • Decay rate
    The speed at which a radioactive compound breaks down, analogous to reaction rate in kinetics.
  • Radioactive nuclei
    Unstable atomic nuclei that undergo radioactive decay, acting as reactants in decay processes.
  • Final concentration
    The concentration of a reactant or product at the end of a reaction or decay process.
  • Initial concentration
    The concentration of a reactant or radioactive nuclei at the start of a reaction or decay process.
  • Chemical kinetics
    The study of reaction rates and the steps involved in chemical reactions.
