    When a uranium isotope \[_{\,\,\,92}^{235}\bigcup \]is bombarded with a neutron, it generates \[_{36}^{89}Kr\]neutrons and:                                                                              [NEET 2020]

    A)  \[_{40}^{91}Zr\]                    

    B)  \[_{\,\,36}^{101}Kr\]

    C)  \[_{\,\,36}^{103}Kr\]  

    D)       \[_{\,\,56}^{144}Ba\]

    Correct Answer: D

    Solution :

    [d] \[\bigcup{_{92}^{235}}+_{0}^{1}n\to Kr_{36}^{89}+3n_{0}^{1}+X_{Z}^{A}\]
       \[92+0=36+Z\]
       \[\Rightarrow Z=56\]
       \[235+1=89+3+A\]
       \[\Rightarrow A=144\]
       So,    \[_{\,\,56}^{144}Ba\] is generated.
