Al2O3 - aluminum oxide (dialuminium trioxide); this oxide is not a cation or anion but a chemical molecular substance.
Al2O3
No subscripts are needed: The formula unit for calcium oxide contains one calcium cation with a charge of +2 and one oxide anion with a charge of -2.
Barium Oxide is BaO.Ba+2 is Barium positive ion (anion).
MgO. Both the magnesium cation and the oxide anion are divalent, so that each ion neutralizes the charge of the other ion.
No, Aluminum oxide is a pure substance.
anion
This ratio in CaO is 1.
Al is the symbol for Aluminum and O is the symbol for oxygen. When oxygen is paired in a compound, it is changed to oxide. The name then is aluminum oxide.
Calcium and Oxygen are the atoms in Calcium Oxide.
Al2O3
An example is calcium(11)oxide. Ca^2+ cation interact with O^2- anion
The molecular formula is CoO Cation is Co^2+^Anion is O^2-^or in other wordscobalt(II) oxide = CoO = Co2+ + O2-
No subscripts are needed: The formula unit for calcium oxide contains one calcium cation with a charge of +2 and one oxide anion with a charge of -2.
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."

Barium Oxide is BaO.Ba+2 is Barium positive ion (anion).
The symbol of the cation of FeCl2 is Fe2+. A cation is a positively charged ion and to find the formula of any compound you must balance the cations with the anions.
