    \[_{95}A{{m}^{241}}+X{{\xrightarrow[{}]{{}}}_{97}}B{{k}^{243}}+Y\] The value of X and Y must be:

    A)  \[X{{=}_{2}}H{{e}^{4}},Y={{2}_{0}}{{n}^{1}}\]

    B)  \[X=2e,Y=a\]

    C)  \[X=a,Y=2e\]

    D)  \[X={{2}_{0}}{{n}^{1}},Y=2{{a}^{4}}\]

    Correct Answer: A

    Solution :

     \[_{95}A{{m}^{241}}+X{{\xrightarrow[{}]{{}}}_{97}}B{{k}^{243}}+Y\] The value of X and Y \[_{95}A{{m}^{241}}{{+}_{2}}H{{e}^{4}}{{\xrightarrow[{}]{{}}}_{97}}B{{k}^{243}}+{{2}_{0}}{{n}^{1}}\] Hence,\[X{{=}_{2}}H{{e}^{4}}\]and \[Y={{2}_{0}}{{n}^{1}}\]
