The `Cu^(2)` having `3d^(9)` congiguration,` Cu^(+)` having `3d^(10)` configuration. The `Cu^(2+)` is ,

Options

A. is more stable
B. is less stable
C. is equally stable
D. stability depends upon the nature of copper salt

Answer

B

Explanation

`Cu^(+)` has `d^(10)` configuration and `Cu^(2+)` has `d^(9)` configuration. Hence `Cu^(2+)` is less stable than `Cu^(+).`
