Re: The exceptions
The exceptions are chromium and copper. Chromium is an exception because a half filled d-sub level is more stable than a partially filled d sub level. The same goes for Copper where it is more stable as a completely filled d-sub level.

Re: The exceptions
It's helpful to remember that when dealing with elements that may be exceptions, fill the orbitals according to n instead of according to energy levels. For example, when filling copper, fill the 4s orbital before 3d.

Re: The exceptions
Another exception that showed up on the midterm was Nitrogen. Because these atoms have a half filled orbital and are stable, they have a higher ionization energy than expected.
Re: The exceptions
The two exceptions are copper and chromium, the rest of the group under those two elements.
