A radioactive nucleus decays as given below:
Which particles are emitted in the sequence?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $β, α, γ$
In a nuclear reaction conservation of charge number and mass number must be conserved.
$∴{^A_ZP}\underset{β}{\longrightarrow}{^A_{Z+1}Q}\underset{α}{\longrightarrow}{^{A-4}_{Z-1}R^*}\underset{γ}{\longrightarrow}{^{A-4}_{Z-1}R}$
