It's important to recognize from the above that chromium is an exception to the normal aufbau progression which would predict 1s2 2s2 2p6 3s2 3p6 4s2 3d4, which is to say that you would normally fill the 4s orbital completely with 2 electrons before starting on the 3d which would then have only 4. Copper is another such exception.
