    \[_{86}{{A}^{222}}{{\to }_{84}}{{B}^{210}}\]. In this reaction how many \[\alpha \] and \[\beta \] particles are emitted                                                                 [BHU 2005]

    A)            \[6\alpha ,\,3\beta \]       

    B)            \[3\alpha ,\,4\beta \]

    C)            \[4\alpha ,\,3\beta \]       

    D)            \[3\alpha ,\,6\beta \]

    Correct Answer: B

    Solution :

               By using \[{{n}_{\alpha }}=\frac{A-{A}'}{4}\] and \[{{n}_{\beta }}=2{{n}_{\alpha }}-Z+Z'\]
