Explanation:
As we know the chemical symbol for copper is Cu while Oxygen is O.
Since this is an ionic compound, the charges of both ions matter
Since the question asked for Copper(II), it suggest that the charge of the copper ion is therefore 2+ and as such will be represented as
The Oxide ion forms when it accepts 2 electrons from another element and as such its representation becomes
Both elements have the same charge so using the "switching charge technique" we would obtain
