In the disintegration series the $_{92}^{238}U\xrightarrow{\alpha }X\xrightarrow{{\beta - }}_Z^AY$ values of $Z$ and $A$ respectively will be
The particles emitted by radioactive decay are deflected by magnetic field. The particles will be
List-$I$ shows different radioactive decay processes and List-$II$ provides possible emitted particles. Match each entry in List-$I$ with an appropriate entry from List-$II$, and choose the correct option.
