Why are Copper and Chromium exceptions? - CHEMISTRY

20151012 · Re: Why are Copper and Chromium exceptions? When doing the electron configurations for these elements, they are exceptions to the general rule because 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.
