Electron Configuration Exceptions

Postby Haya Rabadi 1F » Sun May 06, 2018 11:10 am

Are there more electron configuration exceptions than Cr and Cu? Which ones should we know for the midterm, if need be?

I think for this class Lavelle said we will only be focusing on the first fow for d so (3d). The only exceptions we have to know are Cr and Cu.

Yes, for the midterm I think we only have to know copper and chromium. However, this does show up in some hw problems so the exception where the s shell only has 1 electron is also true for the elements in the column just below Cr and Cu, which are molybdenum and silver. This is for the same reason, because it is most stable when the d subshell is half full (5) or totally full (10).
