The arrangement of electrons in Copper in specific rules in different orbits and orbitals is called the electron configuration of Copper. The electron configuration of Copper is [Ar] 3d10 4s1 if the electron arrangement is through orbitals. 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 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. Discover the correct electronic configuration of Copper (Cu) and why it's an exception to the Aufbau principle. Learn about orbital stability and noble gas notation.
