Electronic configuration of copper: This is expected that

This is expected that the configuration of copper is 3d94s2. However, it turns out that the 3d104s1 configuration is more stable, because that way the 3d subshell is full, which is a far more stable arrangmemnt than 3d9. Due to extra stability of half filled and full filled orbital, Cu have configuration 1s22s22p63s23p63d104s14p0. Learn how to write the electron configuration for copper and its ions using the periodic table or an electron configuration chart. See the correct and incorrect ways to arrange the electrons in orbitals and the exceptions for copper. Learn the electronic configuration of Copper (Cu) and its distribution of electrons in different shells. This guide explains Copper’s atomic structure in a simple and clear way for students and chemistry learners. The electronic configuration of copper is a way to represent the distribution of all the electrons present in copper in different orbitals. Copper (Cu), with atomic number 29, has an electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹ 3d¹⁰.
