The word you are thinking of is an oxide.
Oxygen combined with one other element is an oxide.
The element combined with aluminum in Al2O3 is oxygen.
oxygen is an element not a molecular compound as a molecular compounds are chemically combined and are of more then one element.
it came from the element called sulfur and then combined with oxygen which results in sulfate.
Hydrogen
Nitrogen, oxygen, and the combined element to form nitrate.
The oxidation number of oxygen when combined with fluorine is -1. Oxygen usually has an oxidation number of -2, but when combined with a more electronegative element like fluorine, oxygen's oxidation number becomes -1.
oxygen and hydrogen together they make H2o (WATER DUMBA**)
No, aluminum oxide is not an element. Indeed, nothing called an "oxide" can be an element, as this term indicates that the substance is combined with oxygen and is therefore a compound, not an element.
Helium Oxide would be a compound of 2 elements: helium and oxygen but no such compound exists. Oxygen is just oxygen and nothing else. It is an element in its own right.
These elements are: - oxygen: PbO, PbO2, Pb2O3, Pb3O4 - sulfur: PbS
Oxide is a compound that contains oxygen combined with one other element, while dioxide is a specific type of oxide that contains two oxygen atoms combined with another element. In other words, all dioxides are oxides, but not all oxides are dioxides.
