Answer:

Copper(II) Oxide Formula

The chemical combination of a metal and a non-metal generates an ionic compound. We can determine the formula for an ionic compound based on how many electrons the metal atom loses and how many electrons the non-metal atom gains. The Roman numeral II tells us the electric charge, or oxidation state, of the copper ion, which is +2. This means each copper atom loses two electrons to form the ion Cu+2.

Oxygen is a non-metal and will always gain two electrons, giving it the oxidation state -2. Since each oxygen atom has two extra electrons, the oxide ion is formed, which is O-2.

All ionic compounds have to be electrically neutral, which means the ratio of each element in the compound must contribute enough charge to cancel the charge of the other ion. In the case of the copper(II) ion and the oxygen ion, we can see both ions have equal and opposite charges. This means we only need one of each ion to form the neutral compound copper(II) oxide, which is CuO. Let's discuss the properties of copper(II) oxide
