Since the overall charge of a compound must always be equal to zero (neutral), we need 2 aluminum atoms and 3 oxygen atoms in order to balance out the charge and make the compound neutral. This means that the chemical formula for aluminum oxide is simply Al2 O3.

What is aluminum oxide?

Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al 2O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide.

How do you combine Al and O?

Three Oxygen atoms gains two electrons each ( total of six) from two Al atoms, each Al atom loses three electrons (total of six) to three oxygen atom , in this process each Al atom becomes Al3+ ion and Oxygen atom after gaining two electrons becomes O2− ion. or the formula is Al2O3 .

What is Al2O3 called?

Aluminum Oxide (al2o3)

What will be the formula of the oxide of Al2O3?

The formula of aluminium oxide is Al2O3.

What type of reagent is Al2O3?

Al2O3 is an inorganic chemical reagent with chemical name Aluminum oxide. It is also called as Alpha-Alumina, alumina, alundum or aloxide.

What type of reaction is this Al2O3 -> Al O2?

The reaction given is a decomposition reaction as we are starting with a single reactant and ending with two or more products.

When the equation Al O2 → Al2O3 is balanced the coefficient of Al is?

This is the balanced chemical equation. The coefficient of O2 is 3.
