Question

The half-life period of a radioactive element is same as the mean lifetime of another radioactive element Y. Initially they have the same number of atoms. Then

  1. X will decay faster than Y
  2. X will decay faster than Y
  3. Y and X have same decay rate initially
  4. X and Y decay at same rate always.

The correct answer is: X will decay faster than Y
