Vedclass · Answer

(B) Beta decay can involve the emission of either electrons or positrons. The electrons or positrons emitted in a $\beta$-decay do not exist inside the nucleus. They are only created at the time of emission,just as photons are created when an atom makes a transition from a higher to a lower energy state. In negative $\beta$-decay,a neutron in the nucleus is transformed into a proton,an electron,and an antineutrino. Hence,in the radioactive decay process,the negatively charged emitted $\beta$-particles are the electrons produced as a result of the decay of neutrons present inside the nucleus.
