The half life period of a radioactive element X is same as the mean life time of another radioactive element Y. Initially, they have the same number of atoms. Then
- X and Y decay at same rate always
- X will decay faster than Y
- Y will decay faster than X
- X and Y have same decay rate initially
Answer
(C) Y will decay faster than X
