The half-life of radioactive element depends on:
Correct answer: B. Nature of element
- A. Temperature
- B. Nature of element
- C. Pressure
- D. Amount of radioactive substance
Explanation
The half-life of a radioactive element is primarily determined by the nature of the element itself. Each radioactive isotope has a specific and unique half-life, which is characteristic of that isotope. It is an inherent property of the radioactive element and is not influenced by other factors.T1/2λ = In2T1/2 =In2/λ

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
