This is easy enough: the Answer: [Ar] 3d10 4s1. Explanation: The correct electronic configuration of copper is [Ar] 3d10 4s1. Copper has atomic number 29 and due to the stability of half filled or fully filled orbitals or shells, the electrons from the 4s jumps to the 3d and makes the 3d shell contain 10 electrons. First of all, I hate when this happens!
