Copper has an atomic number of 29. The periodic table's eleventh group contains the d-block element copper. The arrangement of half-filled and fully-filled orbitals is perfectly stable because, as we know, symmetry and a completely filled orbital lead to stability. The 3d10 orbital in the case of copper is fully filled and more stable than the 3d9 orbital. Electronic systems that are partially filled and fully filled are both stable due to the massive amount of energy exchange. It is an extremely high thermal and electrical conductivity metal that is soft, malleable, and ductile. When pure copper is initially exposed to air, it exhibits a pinkish-orange colour.
Hence, the electronic configuration of Copper is Question Image.
