In the disintegration series
$_{92}^{238}U\xrightarrow{\alpha }x\xrightarrow{\beta }_Z^AY$
The value of $Z$ and $A$ respectively will be
${ }_{92}^{238} U$ atom disintegrates to ${ }_{84}^{214} Po$ with a half of $45 \times 10^9$ years by emitting $\operatorname{six} \alpha-$ particles and $n$ electrons. Here, $n$ is
$_{86}{A^{222}}{ \to _{84}}{B^{210}}$. In this reaction how many $\alpha $ and $\beta $ particles are emitted
A radioactive element $_{90}{X^{238}}$ decay into $_{83}{Y^{222}}$. The number of $\beta - $ particles emitted are
An artificial radioactive decay series begins with unstable $_{94}^{241}Pu$. The stable nuclide obtained after eight $\alpha - $ decays and five $\beta - $ decays is
