Question

Complete the following decay schemes.
(a) ${}_{88}{}^{226}\mathrm{Ra}\to \alpha +$
(b) ${}_8{}^{19}\mathrm{O}\to {}_9{}^{19}\mathrm{F}+$
(c) ${}_{13}{}^{25}\mathrm{Al}\to {}_{12}{}^{25}\mathrm{Mg}+$

Answer 1

$$\begin{gathered} \left(\mathrm{a}\right){}_{88}{}^{226}\mathrm{Ra}\to {}_2{}^4\mathrm{\alpha }+{}_{86}{}^{222}\mathrm{Rn} \\ \left(\mathrm{b}\right){}_8{}^{19}\mathrm{O}\to {}_9{}^{19}\mathrm{F}+\overline{e}+\overline{v} \\ \left(\mathrm{c}\right){}_{13}{}^{25}\mathrm{Ar}\to {}_{12}{}^{25}\mathrm{Mg}+e^{+}+v \end{gathered}$$
