Question
What are the electron configurations of the copper ions in YBCO? Are both ions expected oxidation states for copper?
Step 1
Copper has two common oxidation states: +1 and +2. The electron configuration of a neutral copper atom is [Ar] 3d10 4s1. When copper loses one electron to form a +1 ion, the electron is removed from the 4s orbital, resulting in the configuration [Ar] 3d10. When Show more…
