Expert Solution
Concept and Principle:
  • Radioactive decay is the process by which unstable nuclei spontaneously lose energy to become stable. This process will alter the Z and N value till the element becomes stable.

 

  • The rate at which this decay takes place in a given sample of radioactive material is called activity. The half-life for a radioactive element is the time it would take for the activity to reach half its original value.

 

  • Half-life is given by,

t12=0.693λ

Here λ is the decay constant, the decay probability per nucleus per second.
