Answer

Brief Explanations:

  1. The half - life of an isotope is the time it takes for half of the amount of that isotope to decay. So, for silicon - 32 with a half - life of 170 years, in a given rock sample, the amount of silicon - 32 isotope gets divided in half about every 170 years.
  2. The half - life can be used in radiometric dating to determine the amount of an isotope that has decayed since the closure temperature (when the system became closed to the exchange of the isotope) was reached.
  3. Silicon - 32 is the parent isotope and phosphorus - 32 is the daughter isotope. As silicon - 32 decays, the amount of phosphorus - 32 increases. And the amounts of the two are not always equal.

Answer:

  • In a given rock sample, the amount of silicon-32 isotope gets divided in half about every 170 years.
  • The half - life can be used to determine the amount of silicon-32 that has decayed from the time the closure temperature was reached.
