  • question_answer
    The number of\[\alpha -\]and\[\beta -\] particles emitted in nuclear reaction\[_{90}T{{h}^{228}}{{\xrightarrow[{}]{{}}}_{83}}B{{i}^{212}}\]are respectively

    A)  4, 1            

    B)  3, 7

    C)  8, 1            

    D)  4, 7

    Correct Answer: A

    Solution :

     \[_{90}T{{h}^{228}}{{\xrightarrow[{}]{{}}}_{83}}B{{i}^{212}}+x_{2}^{4}\alpha +y_{-1}^{0}\beta \] \[228=212+4x\] or \[4x=16\text{ }or\text{ }x=4\] \[90=83+2x-y=83+8-y\text{ }or\text{ }y=1\]
