    In the disintegration series\[_{92}^{238}U\xrightarrow{\alpha }X\xrightarrow{\beta -}_{Z}^{A}Y\]the values of Z and A respectively will be                               [MP PMT 2003]

    A)            92, 236                                    

    B)            88, 230

    C)            90, 234                                    

    D)            91, 234

    Correct Answer: D

    Solution :

               \[_{92}{{U}^{238}}\xrightarrow{\alpha }{{\,}_{90}}{{X}^{234}}\xrightarrow{{{\beta }^{-}}}\,{{\,}_{91}}{{Y}^{234}}\]
