There's $$\alpha$$-decay. These are Helium particles $$\to \begin{matrix}4\\ 2\end{matrix}He$$ Then you have $$\beta$$-decay. These are electrons $$\to \begin{matrix}~~~0\\ -1\end{matrix}e$$ Don't know what particles in 2,6,7 and 9. You can write the nuclear equations easy in $$\LaTeX$$: $$\begin{matrix}168\\ 77\end{matrix}Ir\to \begin{matrix}4\\ 2\end{matrix}He+\begin{matrix}164\\ 75\end{matrix}Re$$ This is the code: $$\begin{matrix}168\\ 77\end{matrix}Ir\to \begin{matrix}4\\ 2\end{matrix}He+\begin{matrix}164\\ 75\end{matrix}Re$$ $$\overline{\underline{\LARGE{\color{gold}{\star~}}\Large\tt\color{green}{I\;Hope\;this\;Helps!}\LARGE{\color{gold}{~\star}}}}$$
