Chemistry · Bohr model of a hydrogen atom: its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model
Which isotope of hydrogen is/are radioactive in nature?
Which isotope of hydrogen is/are radioactive in nature?
- A. Protium and deuterium
- B. Tritium only
- C. Tritium and deuterium
- D. Only deuterium
Step-by-step solution
Hydrogen has three isotopes: protium (¹H), deuterium (²H), and tritium (³H). Protium and deuterium are stable, while tritium is radioactive, undergoing beta decay with a half-life of about 12.3 years. Therefore, only tritium is radioactive.
