Which of the following isotope of hydrogen is unstable?
Correct answer: C. T3
- A. H1
- B. D2
- C. T3
- D. All of these
Explanation
Tritium is unstable and undergoes beta decay, transforming into helium-3 with a half-life of about 12.3 years, making this the correct answer.

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.
