Respuesta :
The correct answer is Aluminium (Al).
Metal protected from oxidation by adherent oxide coat is Aluminium (Al).
is aluminium oxide metal or a nonmetal?
The right response to this query is that aluminium oxide is a non-metal, not a metal.
Aluminium oxide, often known as alumina or Al2O3, has the chemical formula Al2O3. The bauxite ore is where alumina, which is required to make pure aluminium, is found.
The aspect of sodium chloride is comparable to that of aluminium oxide. Since chlorine gas is deadly and sodium cannot be left open in the air without catching fire, the two elements are highly different from one another. But when they both come together, they create something that can be consumed and is essential to our diet. Aluminium oxide is a non-metal as a result. Instead, aluminium oxide possesses qualities and traits that we list under ceramics.
And for this reason, aluminium that has been oxidized does not qualify as a metal.
