The electron emitted in beta radiation originates from
Inner orbits of atoms
Free electrons existing in nuclei
Decay of a neutron in a nucleus
Photon escaping from the nucleus
In which of the following nuclear reactions, the product is incorrectly matched ?
In a radioactive decay, neither the atomic number nor the mass number changes. Which of the following would be emitted in the decay process
If Alpha, Beta and Gamma rays carry same momentum, which has the longest wavelength
Originally the radioactive beta decay was thought as a decay of a nucleus with the emission of electrons only (Case $I$) . However, in addition to the electron, another (nearly) massless and electrically neutral particle is also emitted (Case $II$). Based on the figure below, which of the following is correct?
A free neutron decays into a proton but a free proton does not decay into neutron. This is because
