Half-life of radioactive element depends upon:
Correct answer: D. None
- A. Amount of element present
- B. Temperature
- C. Pressure
- D. None
Explanation
The half-life of a radioactive element depends only on the nature of the radioactive element. It does not depend on the amount of element present, the temperature, or the pressure.

About Half-life and Rate of Decay
Half-life is the time required for half the unstable nuclei in a sample to decay, and it remains constant for a particular radioactive nuclide. Questions use the exponential decay law, decay constant, activity, remaining quantity and mean life. Radioactive decay is random for individual nuclei but predictable for large samples.
