A) metal atom
B) non metal atom
C) non-metallic anion
D) metallic cation
Correct Answer: D
Solution :
Electronic configuration of Cu is \[1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},4{{s}^{1}},3{{d}^{10}}\] and electronic configuration of \[\text{C}{{\text{u}}^{\text{2+}}}\] is \[\text{1}{{\text{s}}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}3{{d}^{9}}.\] Hence, the given configuration represents metallic cation.You need to login to perform this action.
