WebThere are two main exceptions to electron configuration: chromium and copper. In these cases, a completely full or half full d sub-level is more stable than a partially filled d sub-level, so an electron from the 4s orbital is excited and rises to a 3d orbital. electron configuration exceptions chromium copper Chemistry The Atom WebMay 31, 2024 · Solution. Copper (Cu) has atomic number 29. Its expected electronic configuration is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 9. The 3d orbital is neither half-filled nor fully filled. Hence, it has less stability. Due to interelectronic repulsion forces, one 4s electron enters into 3d orbital.
