    \[_{92}{{U}^{235}}\] nucleus absorbs a neutron and disintegrate in \[_{54}X{{e}^{139}},\,{{\,}_{38}}S{{r}^{94}}\] and X so, what will be product X?

    A)  3-neutrons     

    B)  2-neutrons

    C)  \[\alpha \]-particle      

    D)  \[\beta \]-particle

    Correct Answer: A

    Solution :

    \[_{92}{{U}^{235}}\] nucleus absorbs a neutron and then disintegrate into \[_{54}X{{e}^{139}}{{,}_{38}}S{{r}^{94}}\] and X. Thus, \[_{92}{{U}^{235}}{{+}_{0}}{{n}^{1}}\xrightarrow{{}}\,{{\,}_{54}}X{{e}^{139}}\] \[{{+}_{38}}X{{e}^{94}}+\underset{X}{\mathop{{{3}_{0}}{{n}^{1}}}}\,\]
