In a radioactive decay, neither the atomic number nor the mass number changes. Which of the following would be emitted in the decay process?

Which of the following interactions is responsible for beta decay?

In the uranium radioactive series,the initial nucleus is $_{92}U^{238}$ and the final nucleus is $_{82}Pb^{206}$. When the uranium nucleus decays to lead,the number of $\alpha$-particles emitted will be

Choose the correct nuclear process from the below options $[p : \text{proton}, n : \text{neutron}, e^{-} : \text{electron}, e^{+} : \text{positron}, v : \text{neutrino}, \overline{v} : \text{antineutrino}]$.

$A$ nucleus with mass number $184$ initially at rest emits an $\alpha$-particle. If the $Q$ value of the reaction is $5.5\, \text{MeV}$,calculate the kinetic energy of the $\alpha$-particle in $\text{MeV}$.

Explain the conservation of linear momentum for the radioactive decay of a radium nucleus.
