    Among the following series of transition metals ions, the one where all metal ions have \[3{{d}^{2}}\] electronic configuration is:

    A) \[T{{i}^{3+}},{{V}^{2+}},C{{r}^{3+}},M{{n}^{4+}}\]

    B) \[T{{i}^{+}},{{V}^{4+}},C{{r}^{6+}},M{{n}^{7a+}}\]

    C) \[T{{i}^{4+}},{{V}^{3+}},C{{r}^{2+}},M{{n}^{3+}}\]

    D) \[T{{i}^{2+}},{{V}^{3+}},C{{r}^{4+}},M{{n}^{5+}}\]   

    Correct Answer: D

    Solution :

     \[T{{i}_{22}}=3{{d}^{2}}4{{s}^{2}},T{{i}^{2+}}=3{{d}^{2}}\] \[{{V}_{23}}=3{{d}^{3}}4{{s}^{2}},{{V}^{3+}}=3{{d}^{2}}\] \[C{{r}_{24}}=3{{d}^{4}}4{{s}^{2}},C{{r}^{4+}}=3{{d}^{2}}\] \[M{{n}_{25}}=3{{d}^{5}}4{{s}^{2}},M{{n}^{5+}}=3{{d}^{2}}\]
