Tritium is an isotope of hydrogen whose nucleus triton contains 2 neutrons and 1 proton . Free neutrons decay into `p+bar(e) +bar(n).` If one of the neutrons in Triton decays , it would transform into `He^(3)` nucleus. This does not happen. This is becauseA. triton energy is less than that of a `He^(3)` nucleusB. the electron created in the beta decay proess connot remain in the nucleusC. Both the neutrons in triton have to decay simultaneously resulting in a nucleus with 3 protons, which is not a `He^(3)` nucleusD. Ferr neutrons decay due to external perturbations which is absent in triton nucleus |

Answer» Correct Answer - A Triitum `(""_(1)H^(3))` contain 1 proton and 2 neutrons. A neutron decays as, `nto p+ bare+barv,` the nucleus may have 2 protons and one neutron i.e., tritium will transfrom into a `He^(3)` (2 protons and 1 neutron). Triton energy is less than that of a `He^(3)` nucleus i.e., transformation is not allowed energetically. |
