Electron Configurations Exceptions

Postby FizaBaloch1J » Sat May 05, 2018 7:04 pm

What are all of the electron configuration exceptions we need to be familiar with?

Cu, Cr, and Ag? Are there anymore?

Also, I'm still a little confused on how to do these exceptions, do we just memorize the way they are supposed to be written?

I think molybdenum is part of this list as well, and you just need to remember that those elements will take an e- from the s shell to fill the d shells (singly for Mo and Cr, and doubly for Cu and Ag).

I think in class, Professor Lavelle mentioned that we would only be focusing on the first row of the d-block. So it would just be the Copper and Chromium exceptions.

Just remember that a subshell is more stable if it is half full or full. Thus, 3d^4 becomes 3d^5 and 3d^9 becomes 3d^10.
