The actual configuration is [Ar] 4s^1 3d^10. Copper is anomalous. The atom is more stable with a full 3d shell and a partially filled 4s shell than it would be if it had a full 4s shell and a partially filled 3d shell.
The complete electron configuration for the copper atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d10.
The expected ground-state electron configuration of copper is ; however, the actual configuration is because a full dsubshell is particularly stable. There are 18 other anomalous elements for which the actual electron configuration is not what would be expected.
The electron configuration for copper is Ar 3d10 4s1.
The electron configuration of copper is Ar 3d10 4s1.
The condensed electron configuration for copper is Ar 3d10 4s1.

The electron configuration of copper is Ar 3d10 4s1.
The condensed electron configuration for copper is Ar 3d10 4s1.
The electron configuration of copper (Cu) is Ar 3d10 4s1.
The electron configuration of copper is 1s22s22p63s23p63d104s1.
The electron configuration of copper(II) is [Ar] 3d9 . Copper is [Ar] 3d10 4s1
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
The abbrieviated electron configuration of copper is [Ar] 4s23d9
The ground-state electron configuration for copper (Cu) using noble-gas shorthand is Ar 3d10 4s1.
