    The number of \[\alpha \]-particles and p-particles respectively   emitted   in   the   reaction\[_{88}{{A}^{196}}{{\to }_{78}}{{B}^{164}}\]are:

    A)  8 and 8                

    B)         8 and 6

    C)  6 and 8                

    D)         6 and 6

    E)  8 and 4

    Correct Answer: B

    Solution :

    \[_{88}{{A}^{196}}{{\to }_{78}}{{B}^{164}}\] Number of\[\alpha -\]particles\[=\frac{196-164}{4}=8\] \[_{88}{{A}^{196}}{{\xrightarrow[{}]{-8\alpha }}_{72}}{{X}^{164}}{{\to }_{87}}{{B}^{164}}\] \[\therefore \]Number of p-particles \[=78-72=6\]
