    \[_{92}{{U}^{235}}\] nucleus absorb a neutron and disintegrate in \[_{54}X{{e}^{139}}{{,}_{38}}S{{r}^{94}}\] and X so, what will be product X : [AIPMT 2002]

    A) 3-neutrons

    B) 2-neutrons

    C) \[\alpha \]-particle

    D) \[\beta \]-particle

    Correct Answer: A

    Solution :

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