A) \[M{{g}^{2\text{+}}}\]
B) \[T{{i}^{3\text{+}}}\]
C) \[F{{e}^{2\text{+}}}\]
D) \[C{{u}^{2\text{+}}}\]
Correct Answer: C
Solution :
Electronic configuration of \[Fe{{\,}^{2+}}\] is \[4{{s}^{0}}\,\,\,3{{d}^{6}}\] n = 4 while \[M{{g}^{2+}}\,\,has\,\,n=0\] \[{{\operatorname{Ti}}^{3+}}\,\,has\,\,n=0\] \[C{{u}^{2+}}\,\,has\,\,n=1\]You need to login to perform this action.
