We’re asked to determine the half-life (t1/2) of polonium based on the elapsed time of 14.0 minutes and the remaining amount of 1/16th the initial amount.
Remember that half-life is defined as the time it takes to half the amount of a substance due to decay.
Typically, we discuss this when we´re reviewing radioactive materials such as Uranium or Polonium. Radioactive decay always proceeds as a First Order Rection, therefore we are dealing with a 1st order reaction.
You are experimenting with a radioactive sample of polonium. At the end of 14.0 minutes, exactly 1/16 of the polonium remains. What is the corresponding half life, T1/2, of polonium?
