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.
