Tritium is an isotope of hydrogen whose ...

Tritium is an isotope of hydrogen whose nucleus triton contains 2 neutrons and 1 proton. Free neutrons decay into `p+e^(-)+barV`. If one of the neutrons in triton decays, then it would transform into `He^(3)` nucleus. This does not happen. This is because

A

Triton energy is less than that of a `He^3` nucleus

B

The electron created in the beta decay process cannot remain in the nucleus

C

both the neutrons in triton have a decay simultaneously resulting in a nucleus with 3 protons which is not a `He^3` nucleus .

D

because free neutrons decay due to external perturbations which is absent in a triton nucleus .

What is the name of the isotope of hydrogen which contains 1 proton and 1 neutron?

Assertion: Free Neutron decays into proton, electron and antineutrino Reason : Neutron is unstable outside the nucleus

A: A free proton is stable but inside a nucleus , a proton gets converted into a neutron, position and neutrino (p to n+e^(+)+v) . R: Inside a nucleus, neutron decay (n to p + e^(-)+barv) as well as proton decay are possible, since other nucleons can share energy nad momentum to conserve energy as well as momentum and both the decays are in dynamic equillibrium .

Which of the following atom does not contain the same number of protons and neutrons in its nucleus?

Deuterium is the isotope of hydrogen of mass number 2 , with a proton and a neutron in its nucleus. The chemistry of deuterium is nearly identical to the chemistry of hydrogen, except that C-D bond is slightly (5.0 "KJ" //"mole") stonger than the C-H bond. Reaction rates tend to be slower if a C-D bond as opposed to a C-H bond is broken in a rate limiting step. This effect on the rate is called a kinetic isotope effect.
