Electron Configuration for Copper (Cu, Cu+, Cu2+)

NOTE: Copper is an exception to the rules for writing electron configurations! Video: Cu, Cu +, and Cu 2+ Electron Configuration Notation In writing the electron configuration for Copper the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Copper go in the 2s orbital.
