(a)
Interpretation:
The number of half lives that has gone by for formation of sample which is represented in diagram A should be predicted.
Concept Introduction:
Radioisotopes are the element with same
A half-life time is defined as time taken for a radioactive element to become half of the initial value.
(b)
Interpretation:
The time in minutes gone by for conversion of initial sample to A should be predicted.
Concept Introduction:
Radioisotopes are the element with same atomic number and different mass whose nucleus is unstable and release excess energy with the radiation of alpha, beta, and gamma rays.A half-life time is defined as time taken for a radioactive element to become half of the initial value.
