The decay constant of a radio isotope is λ. If A1 and A2 are it...
Activity is given by
Activity at time t1 is A1 =- λN1
and activity at time t2 is A2 = – l N2 As t1 > t2, therefore, number of atoms remained after time t1 is less than that remained after time t2. That is, N1 < N2.
∴ number of nuclei decayed in (t1 – t2)
and activity at time t2 is A2 = – l N2 As t1 > t2, therefore, number of atoms remained after time t1 is less than that remained after time t2. That is, N1 < N2.
∴ number of nuclei decayed in (t1 – t2)

A constant that represents the probability of decay per unit time. It is denoted by the symbol λ (lambda) and has units of inverse time (e.g. s-1, min-1, etc.). The decay constant is related to the half-life of the isotope by the equation:
λ = ln(2) / t1/2
where t1/2 is the half-life of the isotope. The decay constant is an important parameter in radiometric dating, as it allows scientists to calculate the age of a sample based on the amount of radioisotope remaining and the known decay rate.
