The “I” and “II” in copper oxide represents the number of electrons that the metal has provided when copper oxide is brought into contact with metal. Some uses for copper oxide are: Building copper-based structures. These structures gradually change color due to oxidation.

Given an ion with a charge of +4, how many ions with a charge of -2 will be necessary to create a stable compound? Explain.

Eduardwww [97]

Answer:

$\boxed {\boxed {\sf 2 \ ions}}$

Explanation:

A stable compound has a net charge of 0. Basically, when added, the two ion charges must equal 0 and balance each other out.

We have one ion with a charge of +4. There is another ion of -2. Clearly, these are not balanced yet.

We need more -2 ions to balance it. If we have 2 ions, then their charge is -4 because:

2 * -2 charge = -4 charge

The +4 ion and 2 -2 ions (with a charge of -4) balance each other out and create a net charge of 0. So, <u>2 ions with a charge of -2</u> are necessary to create a stable compound.
