A) \[M{{n}^{2+}}\]
B) \[F{{e}^{2+}}\]
C) \[T{{i}^{2+}}\]
D) \[C{{r}^{2+}}\]
Correct Answer: A
Solution :
Magnetic moment depends upon the number of unpaired electron. Higher the number of unpaired electron in the given ion, higher will be its magnetic moment. \[\mu =\sqrt{n(n+2)}\] where \[n=\] number of unpaired electron \[_{25}Mn=[Ar]4{{s}^{2}},3{{d}^{5}}\] \[M{{n}^{2+}}[Ar]3{{d}^{5}},4{{s}^{o}}\]You need to login to perform this action.
