    The highest oxidation state achieved by transition metal is given by:

    A)  ns electrons

    B) \[(n-1)d\] electrons

    C) \[(n+1)d\] electrons

    D) \[ns(n-1)d\] electrons

    Correct Answer: D

    Solution :

                     The general electronic configuration of d-block elements is\[(n-1){{d}^{1-10}}n{{s}^{1-2}}\]. Hence, the maximum oxidation state is achieved by transition metal is given by\[ns+(n-1)d\]electrons.
