  • question_answer
    A nucleus \[_{n}^{m}X\] emits one a-particle and two \[\beta -\]particles. The resulting nucleus is [AIPMT (S) 2011]

    A)  \[_{n}^{m-6}Z\]         

    B)      \[_{n}^{m-4}X\]          

    C)  \[_{n-2}^{m-4}Y\]      

    D)       \[_{n-4}^{m-6}Z\]

    Correct Answer: B

    Solution :

    \[_{n}^{m}X{{\xrightarrow[{}]{\alpha }}_{n-2}}{{X}^{m-4}}{{\xrightarrow[{}]{2\beta }}_{n}}{{X}^{m-4}}\]
