Homework Help: Chem. Copper and Chromium. Random Q...

Posted by Sarah on Saturday, November 15, 2008 at 1:13am.

So, I have a general chemistry test. My teacher said to know...

"Copper and Chromium exceptions."

I have no idea what that means. I am currently learning about Thermochemistry and the Quantum Theory of an Atom.

Do you have any idea what this might mean??

Thank you for any thoughts!!
