A) \[~[Ne]\text{ }3{{d}^{5}},\text{ }4{{s}^{o}}\]
B) \[\text{ }\!\![\!\!\text{ }Ar\text{ }\!\!]\!\!\text{ }3{{d}^{5}},\text{ }4{{s}^{2}}\]
C) \[\text{ }\!\![\!\!\text{ }Ar\text{ }\!\!]\!\!\text{ }3{{d}^{5}},\text{ }4{{s}^{0}}\]
D) \[\text{ }\!\![\!\!\text{ }Ne\text{ }\!\!]\!\!\text{ }3{{d}^{5}},\text{ }4{{s}^{2}}\]
Correct Answer: C
Solution :
Electronic configuration of \[Mn(25)\]is \[1{{s}^{2}},\text{ }2{{s}^{2}},\text{ }2{{p}^{6}},\text{ }3{{s}^{2}},\text{ }3{{p}^{6}},\text{ }4{{s}^{2}},\text{ }3{{d}^{5}}\] \[\therefore \]Electronic configuration of Mn24-is \[1{{s}^{2}},\text{ }2{{s}^{2}},\text{ }2{{p}^{6}},\text{ }3{{s}^{2}},\text{ }3{{p}^{6}},\text{ }3{{d}^{5}}\] \[\because \] \[M{{n}^{2+}}=[Ar]3{{d}^{5}},4{{s}^{0}}\]You need to login to perform this action.
