The daughter nucleus has one proton more than the parent nucleus.

(C) In $\beta^-$ decay,a neutron inside the nucleus transforms into a proton,an electron,and an antineutrino: $n \rightarrow p + e^- + \bar{\nu}_e$.Since a neutron is converted into a proton,the atomic number $(Z)$ of the daughter nucleus increases by $1$ $(Z_{daughter} = Z_{parent} + 1)$.Therefore,the daughter nucleus has one proton more than the parent nucleus.The correct option is $C$.

View Solution

The intensity of gamma radiation emitted from a source is $I_0$. After passing through a lead sheet of thickness $36 \, mm$,its intensity becomes $I_0/8$. Find the thickness of the lead sheet in $mm$ when the intensity becomes $I_0/2$.

Consider the decay of a free neutron at rest: $n \rightarrow p + e^-$. Show that the two-body decay of this type must necessarily give an electron of fixed energy and,therefore,cannot account for the observed continuous energy distribution in the $\beta$-decay of a neutron or a nucleus.
