Gold Electron Configuration and Properties

The video tutorial by the Crazy Hat Chemist covers the electron configuration of gold, focusing on its atomic structure, valence electrons, and orbital box diagram. It explains the concept of paramagnetism and how to derive quantum numbers for gold. The tutorial also compares the predicted and actual electron configurations of gold, highlighting the differences and similarities with copper and silver. The video concludes with a discussion on the importance of understanding these configurations for chemistry studies.
