The half - life period of a radioactive element x is same as the mean life time of another radioactive element yInitially both of them have the same number of atoms. Then,n |

Answer» X and Y decay at same rate always i.e. `T_X gt T_Y THEREFORE lambda_X lt lambda_Y` `because R=lambdaN` and N is same for both, `therefore R_X lt R_Y` or `R_Y gt R_X` i.e. Y will decay faster than X. |
