    The outer electronic configuration of transitional elements is

    A)  \[(n+1){{s}^{2}}n{{d}^{\,1\,-\,5}}\]

    B)  \[(n-1){{s}^{2}}{{p}^{6}}(n-1)\,{{d}^{1-10}},n{{s}^{1,\,2}}\]

    C)  \[n{{s}^{2}}(n+1){{d}^{1\,-\,10}}\]

    D)  \[(n-1){{s}^{2}}n{{d}^{1\,-\,2}}\]

    E)  \[(n-2){{s}^{2}}n{{d}^{1\,-\,3}}\]

    Correct Answer: B

    Solution :

                    \[(n-1){{s}^{2}}{{p}^{6}}(n-1){{d}^{1-10}}n{{s}^{1,\,\,2}}=\]electron configuration of transition elements.
