Answer:
Cation is represented as Au⁺. The anion in the compound is the oxide ion which can be represented as O²⁻
Answer:
cation is O
The anion is Au
Explanation:
Au (gold) is in Group 6 so it needs to gain 2 electrons to complete its outer shell
O (oxygen) is in Group 2 so it needs to lose 2 electrons to complete its outer shell.
As Au (gold) gains electrons it becomes an ion with a negative charge (anion)
As O (oxygen) loses electrons it becomes a positively charged ion (cation)
