Of the following outer electronic configurations of atoms, the highest oxidation state is achieved by which one of them [AIEEE 2004]

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

B) \[(n-1){{d}^{5}}n{{s}^{1}}\]

C) \[(n-1){{d}^{8}}n{{s}^{2}}\]

D) \[(n-1){{d}^{5}}n{{s}^{2}}\]

Correct Answer: D

Solution :

\[(n-1)\ {{d}^{5}}n{{s}^{2}}\] can achieve the maximum oxidation state of + 7.
