 (a) \(^{226}_{86}Ra\) \(\longrightarrow\)\(^4_2\alpha\) + \(^{222}_{86}Em\)

Em (Emanation) ≡ Rn (Radon) 

Here, α particle is emitted and radon is formed.

(b) \(^{19}_{8}O\) \(\longrightarrow\) \(\bar{e}\) + \(^{19}_{9}F\)

Here, \(\bar{e}\) ≡ \(^0_{-1}\beta\) is emitted and fluorine is formed.

(c) \(^{228}_{90}Th\) \(\longrightarrow\) \(^4_2\alpha\) + \(^{224}_{88}Ra\)

Here, α particle is emitted and radium is formed.

(d) \(^{12}_{7}N\) \(\longrightarrow\) \(^{12}_{6}C\) + \(^0_{1}\beta\)

\(^0_{1}\beta\) is e+ (positron)

Here, β+ is emItted and carbon is formed.
