  • question_answer
    The transition element have a characteristic electronic configuration which can be represented as [MP PMT/PET 1988; MP PMT 1989]

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

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

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

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

    Correct Answer: D

    Solution :

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