Question
Complete the following radioactive reaction:
\[ {}^{\cdots\cdots}_{\cdots\cdots}\mathrm{X} \longrightarrow \mathrm{Y} + {}^{4}_{2}\mathrm{He} \longrightarrow {}^{234}_{\;91}\mathrm{Z} + {}^{\;\;0}_{-1}\mathrm{e}\]

Solution 1
\[{}^{238}_{92}X \rightarrow {}^{234}_{90}Y + {}^{4}_{2}\mathrm{He} \rightarrow {}^{234}_{91}Z + {}^{\;\;0}_{-1}e\]
Solution 2
\[{{}^{238}_{92}\mathrm{X}\xrightarrow{\alpha}{}^{234}_{90}\mathrm{Y}\xrightarrow{\beta^-}{}^{234}_{91}\mathrm{Z}}\]
