In a given reaction
ZXA → Z + 1YA → Z - 1KA - 4 → Z - 1KA - 4
Radioactive radiations are emitted in the sequence of
-
- α, β, γ
- γ, α, β
- β, α, γ
- γ, β, α
Correct Option: C
Increase of charge number by 1 indicates β emission. Decrease of mass number by 4 and charge number by 2 indicates α emission. No change of mass number and charge number indicates γ-emission.
