  • question_answer 49)   The largest oxidation number exhibited by an element depends on its outer electronic configuration. With which of the following outer electronic configurations the element will exhibit the largest oxidation number? (a) \[3{{d}^{1}}4{{s}^{2}}\]                           (b)\[3{{d}^{3}}4{{s}^{2}}\]                           (c)\[3{{d}^{5}}4{{s}^{1}}\]                                (d)\[3{{d}^{5}}4{{s}^{2}}\]

    Answer:

      (d) \[3{{d}^{5}}4{{s}^{2}}\]configuration belongs to \[M{{n}_{25}}\], its oxidationstate varies between +2 to +7.
