Opals can actually be made from metals and non-metals and are of perticluar interest in modern Nanotechnology because they posess something called a photonic bad gap. This basically allows no light of a certain wavelength to propagate through the structure. Natural opals are formed from silicon dioxide otherwise known as silica. In research opals are commonly created from silica, silicon, PMMA and polystyrene.
Nails are metal.
it can be a metal or nonmetal or metalliods
nonmetal
Sodium (metal) reacts with chlorine (nonmetal) to form sodium chloride. Magnesium (metal) reacts with oxygen (nonmetal) to form magnesium oxide. Aluminum (metal) reacts with sulfur (nonmetal) to form aluminum sulfide. Lithium (metal) reacts with nitrogen (nonmetal) to form lithium nitride. Potassium (metal) reacts with fluorine (nonmetal) to form potassium fluoride. Calcium (metal) reacts with phosphorus (nonmetal) to form calcium phosphide. Barium (metal) reacts with iodine (nonmetal) to form barium iodide. Titanium (metal) reacts with carbon (nonmetal) to form titanium carbide. Iron (metal) reacts with chlorine (nonmetal) to form iron(III) chloride. Zinc (metal) reacts with sulfur (nonmetal) to form zinc sulfide.
Uranium is a metal, rather than a nonmetal, or metalloid.
