Tritium is an isotope of hydrogen whose nucleus triton contains 2 neutrons and 1 proton. Free neutrons decay into 
. If one of the neutrons in Tritium decays, it would transform into 
nucleus. This does not happen. This is because:
A
Tritium energy is less than that of a 
nucleus
nucleus
B
The electron created in the beta decay process cannot remain in the nucleus
C
Both the neutrons in triton have to decay simultaneously resulting in a nucleus with 3 protons, which is not a 
nucleus.
nucleus.
D
Free neutron decay due to external perturbations which is absent in triton nucleus
Text Solution
Verified by ExpertsThe correct answer is:
A
Tritium 
contains 1 proton and 2 neutrons. A neutron decays as 
, the nucleus may have 2 protons and one neutron, i.e., tritium may transform into 
( 2 protons and 1 neutron).
Tritium energy is less than that of 
nucleus, i.e., transformation is not allowed energetically.
