Interpretation Introduction

Interpretation: Number of atoms present in the Iodine -131 should be calculated

Concept Introduction:

  • Half-life period: The time required to reduce the half of its original value.
  • This is denoted by: t1/2
  • This term is popularly use in nuclear chemistry, to describe the stability & instability of atoms or radioactive decay.
  • For determination of first order rate constant K in half –life period we use

    K=0.693t1/2  Equation.

  • The half-life in first order does not depend upon the initial concentration.

    Formula:

  • Age calculation:

    lnNtN0=-kt

  • Calculate the age and rate constant:

    K=0.693t1/2

To Determine: Number of atoms present in the Iodine -131 by using the given data.

Given:

Half-life period of I131 =8.1days.
