The electronic conguration `1s^(2)2s^(2)2p^(6)3s^(2)3d^(9)` represnts a

A

Metal atom

B

Non-metal atom

C

Non-metallic anion

D

Metallic cation

Text Solution

Verified by Experts

The correct Answer is:
D
The electronic configuration of Cu is
`1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(10)4s^(1)`
`Cu^(2+)rarr 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)3d^(9)`.
This shows the configuration of `Cu^(2+)` i.e. metallic cation.
