There is no such thing as dialuminum trioxide because the combination of 2 aluminums and 3 oxygens creates an IONIC COMPOUND, since it is between a metal and nonmetal, and ionic compounds are not named the same way as binary molecular compounds which is the way it is named in the question. In naming a binary molecular compound you denote each element with the number of each atom in the formula, which was done with " dialuminum trioxide", except this molecule is NOT a binary molecular compound, but an IONIC COMPOUND. To name an ionic compound you simply drop the ending to the least metallic element (oxygen) and add an -ide. So the outcome is ALUMINUM OXIDE.
2 Al and 3 O
The formula for dialuminum hexafluoride is Al2F6. It consists of two aluminum atoms bonded to six fluorine atoms.
Its standard name is, Nitrogen(III) Oxide.
Arsenic trioxide refers to Diarsenic trioxide = As2O3 . It is not to be confused as AsO3 which does not exists.
The formula for xenon trioxide is XeO3.

Xenon Trioxide
Its standard name is, Nitrogen(III) Oxide.
Granite is primarily composed of quartz, feldspar, and mica minerals. It is a hard, durable rock with a crystalline structure. Granite is resistant to chemical weathering and is typically non-reactive with most acids and alkalis.
Dinitrogen Trioxide: N2O3
radon trioxide
Sulfur trioxide is a byproduct of sulfuric acid. In large quantities, sulfur trioxide can be deadly. For the most part, small quantities of sulfur trioxide will not hurt you.
Arsenic trioxide refers to Diarsenic trioxide = As2O3 . It is not to be confused as AsO3 which does not exists.
The name of the compound Cl2O3 is dichlorine trioxide.
Phosphorous Oxide
The formula for xenon trioxide is XeO3.
