Answer

(a) One proton is emitted:

As the atomic number is given as 11, the number of protons will be also 11,

1123X⟶ 1022A++11p_{11}^{23}\text{X} \longrightarrow \space _{10}^{22}\text{A} + _{+1}^{\enspace 1}\text{p}

(b) one β particle is emitted

1123X⟶ 1223B+−10e_{11}^{23}\text{X} \longrightarrow \space _{12}^{23}\text{B} + _{-1}^{\enspace 0}\text{e}

(c) one α particle is emitted
1123X⟶ 919C+ 24He_{11}^{23}\text{X} \longrightarrow \space _{9}^{19}\text{C} + \space _{2}^{4}\text{He}
