A) \[{{d}^{3}}{{s}^{2}}\]
B) \[{{d}^{5}}{{s}^{1}}\]
C) \[{{d}^{5}}{{s}^{2}}\]
D) \[{{d}^{8}}{{s}^{2}}\]
Correct Answer: C
Solution :
\[Mn=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}},3{{p}^{6}}3{{d}^{5}},4{{s}^{2}}\] Its electronic structure suggest that it should has a maximum oxidation state \[+7\]. Important oxidation state of \[Mn\] are \[+2\] (in \[M{{n}^{2+}}\] salts), \[+3\] (in \[M{{n}_{2}}{{O}_{3}}\]), \[+4\](in \[Mn{{O}_{2}}\]) and \[+7\] (in \[KMn{{O}_{4}}\]).| Element | Electronic structure | Oxidation state |
| \[Mn\] | \[[Ar]\,3{{d}^{5}},4{{s}^{2}}\] | \[-3,-1,0,1,2,\] \[3,4,5,6,7\] |
