oxygen and hydrogen together they make H2o (WATER DUMBA**)
Hydrogen
oxygen is an element not a molecular compound as a molecular compounds are chemically combined and are of more then one 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.
Oxygen is an element. it is not a compound.
It isn't a element, as an element is one atom. It would be a compound if the elements chemically combined, but if they didn't, its a misture
Oxides are the type of compound that is typically formed when an element is burned in air. Oxides are compounds composed of an element combined with oxygen.
ammonium nitrate is a compound. It is neither element nor mixture.
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.
Oxygen combined with one other element is an oxide.
The element combined with aluminum in Al2O3 is oxygen.
Since Oxygen exists in combined state in nature, it is termed as a molecular element and Sucrose is a molecule of Carbon, Hydrogen and Oxygen with no charge on it, hence it is considered a molecular compound.
Oxygen is an element
