The correct electronic configuration of Cu+1 is:
Correct answer: D. [Ar]3d10
- A. [ Ar]4s'3d8
- B. [Ar]4s'3d54s2
- C. [Ar]3d104s1
- D. [Ar]3d10
Explanation
The electronic configuration of Cu is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰.When Copper loses one electron to form Cu+1 ion, it loses the 4s¹ electron. Therefore, the electronic configuration of Cu+1 is 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ or can be written as [Ar][3d10] as well.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
