The electronic configuration of copper (Cu), with an atomic number of 29, is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰. This unique configuration is characterized by one electron in the 4s orbital and ten electrons in the 3d orbital, which differs from the typical filling order. Copper’s 3d¹⁰ configuration in the third energy level (shell) is attributed to the increased stability of a half-filled or fully-filled d subshell. This electronic configuration of copper is responsible for its exceptional electrical conductivity and has made it a valuable material in various industrial applications, including electrical wiring and electronics. The electronic configuration of copper is often a topic of interest due to its peculiar arrangement of electrons.
Electronic Configuration of Copper in Shells
Copper’s electronic configuration is usually represented as 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰. This configuration highlights the distribution of electrons in different energy levels, or shells. The 1s², 2s², and 2p⁶ represent the first and second shells, while the 3s² and 3p⁶ denote the third shell. The 4s¹ and 3d¹⁰, which is unusual, belong to the fourth shell. Copper’s anomalous electronic configuration in the 4s and 3d orbitals is due to the energy levels of these orbitals.

Copper’s electrons are distributed across various shells, with the KLMN shell containing the most significant number of electrons. In this context, K represents the first shell, L the second shell, M the third shell, and N the fourth shell. Copper’s electronic configuration in these shells can be summarized as follows:
– K shell (1s²)
– L shell (2s² 2p⁶)
– M shell (3s² 3p⁶ 4s¹ 3d¹⁰)
– N shell (empty)
