Al2O3
The ionic compound formed between Al^3+ and S^2- ions would have the formula Al2S3. This formula ensures that the positive and negative charges balance out in the compound, with two aluminum ions combining with three sulfide ions.
The chemical formula for oxygen is O2 and for individual oxygen atom its symbol is O. Gases such as oxygen exist as diatomic molecules.
The formula for the oxide ion is O2-, and the formula for the nitrate ion is NO3-.
The chemical formula for oxygen is O2, indicating that molecular oxygen consists of two oxygen atoms bonded together.
Let's break it down: Al3 = 3 atoms 02 = 2 atoms Add that up = 5 atoms Since the coefficient is 2, we multiply that by 2 Hence there are 10 atoms
Al2O3
The equation for Al3O3 is Al3 + O2.
Al2O3, aluminium oxide. Remember the numbers must be subscripts.
The ionic formula for Aluminium Oxide is Al2O3. This compound is formed by the combination of aluminium (Al) cations with a +3 charge and oxygen (O) anions with a -2 charge.
When Lithium and Oxygen combine, they form lithium oxide with the chemical formula Li2O. The balanced chemical equation for this reaction is 4Li + O2 -> 2Li2O.
The likely formula of the compound formed between calcium (Ca) and oxygen (O) is CaO. Calcium has a valency of +2, while oxygen has a valency of -2, so one calcium atom will combine with one oxygen atom to form a stable compound.
Li2O The reaction eq'n is 4Li(s) + O2(g) = 2Li2O(s)
The ionic compound formed between Al^3+ and S^2- ions would have the formula Al2S3. This formula ensures that the positive and negative charges balance out in the compound, with two aluminum ions combining with three sulfide ions.
The formula for the binary ionic compound aluminum oxide is Al2O3. It is composed of aluminum cations (Al3+) and oxide anions (O2-). The compound forms in a 2:3 ratio to balance the charges and achieve neutrality.
Al2O3 contains aluminum ions Al3+ and oxide ions O2-, though it is normally a solid.

Na, Rb, Al3+, and S2- do not have a noble gas configuration as they do not have the complete outer shell of electrons like a noble gas. O2, Br, Ca, and O2- have noble gas configurations as they either have a complete outer shell of electrons or have gained/lost electrons to achieve a stable noble gas configuration.
