Chapter 21, Problem 21.82QP
Interpretation Introduction

Interpretation:

The constituents of wine contain carbon, hydrogen, and oxygen atoms. A bottle of wine was sealed about six years ago. It should be found the isotope that used to determine the age of wine bottle.

Concept Introduction:

  • Unstable nuclei emit radiation spontaneously to become stable nuclei by losing energy. This process of emission of radiation by unstable nuclei is known as radioactive decay
  • These emitted radiations may be alpha radiations(α), beta radiations(β) or gamma radiations(γ)
  • These unstable nuclei are the nuclei with more than 83 protons and which do not lie within the belt of stability.
  • Radioactive decay is in the first order kinetics. Rate of radioactive decay at a time t is,
  • Rate of decay at a time 't' = k Nk-Firstorderrateconstant and its unit is t1N-numberofradioactivenucleipresentattime't

    Suppose the number of radioactive nuclei at time zero is N0 and at a time t is Nt,

    lnNtN0=-kt

  • Half-life of radioactive decay is the time required for a radioactive sample to decay to one half of the atomic nucleus.
  • Half-life of the radiation,  t1/2=0.693k

    Half-life and rate constant for radioactive isotopes vary greatly from nucleus to nucleus. 

To find: the isotope that used to determine the age of wine bottle
