Vedclass · Answer

(D) The half-life $(T_{1/2})$ of a radioactive substance is defined as the time required for half of the radioactive nuclei in a sample to decay.It is given by the formula $T_{1/2} = \frac{\ln(2)}{\lambda}$,where $\lambda$ is the decay constant.The decay constant $\lambda$ is a characteristic property of the radioactive isotope and is independent of external physical conditions such as temperature,pressure,or the initial amount of the substance present.Therefore,the half-life depends solely on the nature of the radioactive element.

The half-life of a radioactive element depends upon:
