Interpretation: The percentage of radioactive C-14 should be determined by using the following data listed in question.
- Half-life period: The time required to the reduce to half of its original value.
- This is denoted by
- 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
- The half-life in first order does not depends upon the initial concentration.
Determine: the percentage and rate constant is being determine by considering the age of carbon-14 isotope.
The number of disintegration is directly proportional to the number of radioactive nuclei
