A) \[[Ne]\,3{{d}^{5}},4{{s}^{0}}\]
B) \[[Ar]\,3{{d}^{5}},4{{s}^{2}}\]
C) \[[Ar]\,3{{d}^{5}},4{{s}^{0}}\]
D) \[[Ne]\,3{{d}^{5}},4{{s}^{2}}\]
Correct Answer: C
Solution :
Electronic configuration of Mn (25) is \[1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},4{{s}^{2}},3{{d}^{5}}\] \[\therefore \] Electronic configuration of Mn21is \[1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},3{{d}^{5}}\] \[\because \] \[M{{n}^{2+}}=[Ar]3{{d}^{5}},4{{s}^{0}}\] \[=[Ar]\]You need to login to perform this action.
