no because if the metals were reactive then they would react with elements in the air non reactive metals are found in there native state like gold and silver.
Yet they are found as ores, compounds, often oxides or carbonates. And can be extracted using carbon to reduce the metal compound to the pure metal.
yes
Aluminium is found not in a free state because it is so reactive that it reacts with oxygen.
Pure native metals are considered minerals. Mixed metals are considered alloys.
yes , sulphur have ores. such ores are called sulphide ores. these sulphide ores are purified by the process called roasting. this is the process which involves heating with oxygen and then reducing into original metals. eg: copper sulphide, zinc sulphide, etc.
Metallic ores provide the raw materials for the production of metals.
Mined of metal ores depend on the position of the metal in electrochemical or activity series but metals can be extract through electrolysis and reduction process.
potassium, nickel, carbon
Yes metals are found in rocks called ores. Most metals are more reactive and are found combined with other elements in rocks.
That is not a very precise question. I will assume first, that you mean metallic elements, since 'metals' would include brass, bronze, pewter, and steel! The other thing that would be needed are sharp dividing lines between "very reactive" and "fairly reactive", and between metallic and semi-metallic elements. And finally, does the question mean [b]always[/b] found as ores? Copper [b]can[/b] be found as the metal in nature, but it is now very rare, and copper ores are the usual source of copper metal. Gold is nearly always found as the metal, but there is a rare gold telluride ore. Have a modern (IUPAC) periodic table in front of you for the rest of this answer. Group 1 contains only very reactive metals. Be from group 2 is arguably only fairly reactive; the other elements in this group are very reactive. Group 3, including all of the lanthanide and actinide elements, would count as very reactive, as would Ti from group 4. Zr and Hf are borderline between fairly and very reactive. Groups 5 to 12 would all count as fairly reactive metals, but Os, Ir, Pt, Au are usually found as metals rather than ores, while Ru, Rh, Pd, Ag, Hg, and Cu are sometimes found as metals. From group 13 Al and Tl count as very reactive, Ga and In as very/fairly borderline, while B is not a metal. In groups 14, 15, and 16, only Sn, Pb, Bi, and Po could be counted as metals, and they would only be fairly reactive. There are no metals in groups 17 and 18.

Quick and simple answer is that metals are solid and therefore are affected by the gravity of the Earth more than gases. Therefore gases are in the air and solids are on the surface or under the surface of the Earth.
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
False because an ore is any rock that contians any metal... Best Wishes, Shady Qubaty
reactive metals can often be extracted by electrolysis where there ore is disolved into a solvent and an electric current is passed through.
Metals are usually found in the Earth's crust, in the form of ores.

unreactive metals, such as gold
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
