An aluminum ion has a charge of +3, and an oxide has a charge of -2. What would be the product of a reaction between these two elements

The product of the reaction between  aluminium ion with a charge of +3, and an oxide with a charge of -2 is Al₂O₃ .

The aluminium ion has a charge of +3 and the oxide has a charge of -2. The product of there reaction can be explained below.

The simple technique use here is exchanging the charges. The aluminium is a cation(positive charge) and it has a positive charge of 3.  The oxygen is an anions(negative charge) and it has a negative charge of negative 2.

For the combined product to be electronically neutral, the 2 aluminium atom has to donate 3 of its outer electrons to the 3 oxygen atoms. This kind of bonding is called ionic or electrovalent bonding

Therefore, the product formed will be as follows:

Al³⁺ + 0²⁻ → Al₂O₃

The product of a reaction between these two elements is .

Explanation:

The oxidation state of an ion in a compound is equal to its charge.

The aluminum having a charge of +3 because oxidation state is +3

The oxide is having charge of -2

The product of these reactants will produce a chemical compound.

The compound formed is  i.e Aluminium oxide. The compound while getting formed will share the charge and cation A+ will have the charge of anion and anion will have the charge of cation. This will result in a compound as there should be a neutral charge on the compound formed.

The +3 charge of the cation Al+ will go to anion oxide O2- and the charge of anion -2 will go with cation Al+.
