${\mathrm{ }}_7^{14}\mathrm{N}+{\mathrm{ }}_2^4\mathrm{ }\mathrm{\alpha }\to {\mathrm{ }}_8^{17}\mathrm{O}+{\mathrm{ }}_{\mathrm{Z}}^{\mathrm{A}}\mathrm{X}$

From conservation of charge

$7+2=8+\mathrm{Z}$

$\mathrm{Z}=1$

From conservation of mass number

$14+4=17+\mathrm{A}$

$\mathrm{A}=1$

$\therefore \mathrm{ }\mathrm{ }{ }_1^1\mathrm{X}$is proton.
