Earth has a strongly oxidizing atmosphere. Combine that with water which can contain acids and other solutes and it becomes difficult for a metal to remain in its elemental state for long periods of time. A mass of metal may be buried for millions if not billions of years.

Where are metals formed?
Metals are usually found in the Earth's crust, in the form of ores.
Rocks that contain a metal oxide are called ores true or false?
False because an ore is any rock that contians any metal... Best Wishes, Shady Qubaty
How are minerals extracted from their ores?
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.
Where is neptunium found in nature?
Neptunium exist in nature in: - uranium ores, in extremely traces concentrations - in areas of past nuclear weapons tests
Are all metals found in ores?
"No, gold, silver, and platinum are some of the metals which are not ores". Yes, these metals do occur as nuggets of native element, and are dredged, or panned from stream, and river sediments, but there are many sulfides, and oxides of these, and other metals as well. These oxides, and sulfides are the Ore Minerals sought after by prospectors, and mined from in sittu Hard Rock Deposits.
Are metals are found in rocks called ores?
Yes metals are found in rocks called ores. Most metals are more reactive and are found combined with other elements in rocks.
Where are most metals found?
Metals are usually found in the Earth's crust, in the form of ores.
What are metal oars?
Metal ores are metallic elements found in compounds with other elements in nature. These ores are then separated to produce pure metals.
Do metals only come fron ores?
Yes, metals do only come from ores and pure metals also are found in the Earth's crust.
Where are metals formed?
Metals are usually found in the Earth's crust, in the form of ores.
Are transition metals often found in ores?
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.
Which metals are not found in ores?
There are a lot more than five. For example, all the alkali and alkaline earth metals are not found naturally in pure form but occur only in compounds. It's actually unusual for a metal to exist in pure form in nature; most of them occur only in compounds.
Which metal ores are found naturally?
unreactive metals, such as gold
What metals are fairly reactive and found as ores?
potassium, nickel, carbon
What are the common ores in iron and lead?
Iron is usually found in nature as an oxide, the most common being hematite and magnetite. Lead usally appears with other metals, especially silver. The most common ore used as commercial feedstock is galena.
Which elements found in nature have mainly radioactive isotopes?
uranium ores
Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
