Question
In the nuclear decay given below,
the particle emitted in the sequence are
-
β, α, γ
-
γ, β, α,
-
β,γ, α
-
α, β,γ
Solution
A.
β, α, γ
In a nuclear reaction conservation of charge number and mass, the number must hold good.
Alpha particles are positively charged particles with charge +2e and mass 4 m. Emission of an α particle reduces the mass of the radionuclide by 4 and its atomic number by 2. β- particles are negatively charged particles with rest mass as well as charge same as that of electrons. γ particles carry no charge and mass.
Radioactive transition will be as follows.
