Homework 1E.7
For 1E. 7 b), in the configuration given, does it matter that the second electron in the 2p state has a downward spin? Or does it disqualify the configuration from being a ground state configuration?

Yes! This matters because it violates Hund's rule, which states not only that each orbital is occupied by a single electron first, but also that all the unpaired electrons need to have parallel spins (the same spin direction).

Re: Homework 1E.7
I believe part C violates Aufbau's Principle because the 2s orbital must be occupied with 2 electrons with parallel spins before electrons can be arranged into the 2p orbital. There's 1 electron in the 2s orbital and 1 electron in the 2p orbital.
