Configuration Notation

For electron configurations of atoms with p and d orbitals, is it necessary to specify the orbital type in the configuration e.g. 2px1 2py1 or is it acceptable to put them all together e.g. 2p2?

Yes because in the example he gave in class he specified what type of p orbitals. So I think we will need to do that for the test.

if you just write 2p2 it does not specify what the ml quantum number would be. So you would need to include (for example: 2px1, 2py1)

Can someone explain why copper and chromium are exceptions for electron configurations?

In reference to chromium and copper, I think the professor is going to go over this exception this week.

For most elements, the orbital filling rule is based on average energy levels of various orbitals. These energy levels are different for every element, but the general trend of which orbitals are higher in energy is pretty uniform. For copper and chromium, it is mainly an empirical result that the orbitals fill differently due to their energy levels, but there is not a simple reason for why this is the case.
