The formula of Aluminum oxide is Al
2
O
3
. This is because it forms an ion with a charge of
+3
along with oxygen ion atom. This always ends in forming an ion with a charge of -2.
What is the oxidation number of Al2O3?
This is a neutral compound. Hence the sum of the oxidation numbers of all the elements in this compound is 0. Hence the oxidation number of O in Al2O3 is
-2
.
What is the formula name for Al2O3?

aluminum oxide
| Chegg.com.
Is Al2O3 acidic or basic?
Aluminum Oxide
Aluminium oxide is amphoteric. It has reactions as both a
base and an acid
.
Why is Al2O3 written?
When writing a formula, the amount of positive charge from the cations must equal the amount of negative charge from the anions, resulting in no net charge. …
If we combine two Al3+ ions and three O2- ions, and use subscripts to indicate the number of each ion in
the formula, we obtain Al2O3 as the empirical formula.
What is Li2O called?
