\]
What are the respective numbers of \(\alpha\) and \(\beta\) particles emitted respectively in the following radioactive decay?
\[
{}^{200}_{90}X \rightarrow {}^{168}_{80}Y
\]
Show Hint
For \(\alpha\)-decay, mass number decreases by \(4\) and atomic number decreases by \(2\). For \(\beta^{-}\)-decay, mass number remains same and atomic number increases by \(1\).
