The electronic configuration, `1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 3d^(9)`, represents 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+) to 1s^2 2s^2 2p^6 3s^2 3p^6 3d^9`
This shows the configuration of `Cu^(2+)` i.e., metallic cation.
