Most metals oxidize under the right conditions. Gold, platinum and palladium do not oxidize at room temperature, which is the reason they are used in jewelry and electronics. Stainless steel, titanium, tantalum and niobium are highly resistant to oxidation.
Rust is iron oxide. The forms Fe2O3, Fe3O4, and FeO are the most common. Rust is a porous coating, which allows air and water to get in contact with the base metal, and the rusting process continues. Iron and steel products except the many stainless steels will readily oxidize or rust in the presence of oxygen and water in the earth's environment. Stainless steels contain enough chromium (minimum of 13% Cr by weight) to retard the rusting process. The chromium contained in the alloy forms an oxide (oxidation!) that provides a thin barrier protecting the steel and making it "stainless." This does not mean it won't corrode eventually--only that it is highly resistant to oxidation.
Pure titanium is exceedingly resistant to attack from water and air. It can develop an extremely thin skin of oxidized titanium that provides a passive barrier separating the metal from its environment.
Anodization is a deliberate oxidization of aluminum (aluminum), titanium, magnesium, zinc or niobium that forms a passive barrier that protects the metal from further destruction.
Copper away from contact with other metals will oxidize to a strongly protective barrier coating, making the metal underneath durable. Copper alloyed with zinc (brass) and tin (bronze) also only oxidizes superficially, making these alloys stand up well to corrosion.

∙ 12y agoStrictly, only iron and its alloys "rust" and all other metals do not, because the verb "rust" strictly means to form iron oxide from iron. The more general term for metals is "corrode", and almost all elemental metals except gold, platinum, iridium, osmium, rhodium, ruthenium, and palladium corrode under some conditions that are at least moderately prevalent on earth. Any metal can be dissolved in some liquid under laboratory conditions, so that this kind of question is qualitative at best.

∙ 12y agoThe most common metal that is highly resistant to corrosion is Gold. Other fairly common highly corrision-resistant metals include, Platinum, Rhodium, Palladium and Irridium. These metals are in the group called Nobel metals. Silver, Copper and Nickel are also Nobel metals, but they aren't as highly corrosion-resistant.
Oops... I was considering only elemental metals (not alloys). Of course some grades of Stainless Steel may also be considered corrosion-resistant.
Gold is also corrosion resistant, and Aluminium, on contact with air creates a layer of aluminum oxide that protects it from damage.

What are two metals that tarnish quickley in air?
Silver and copper! both will oxidize noticably.
Which property of metals make them suitable for use in jewelry?
The most important property of the metals that are suitable for jewellery is that they do not oxidize easily. These metals are at the bottom of the activity series, and they are copper, silver, mercury, platinum, gold.
Which metal rusts first copper or iron?
Neither. Only iron rusts. Other metals oxidize.
Will metal get affected in sugar water?
yes, some metals will rust in various ways and at different speeds. However only metals with iron in them will rust. Other metals will either oxidize or just remain the same. So the answer is partly yes, partly no. It depends what metal specifically.
How can sugar water make metals rust?
it has water, so I'm assuming yes. And remember, the only metals that rust have iron in them. For example, copper does not rust. However, it does oxidize, turning it that funny green color. Be careful of the terminology you use.
How does orange juice oxidize metals?
it doesn't
What metals oxidize under UV light?
Metals are not oxidized by UV radiation.
Of the metals Pb Hg Na and Ca which is the most difficult to oxidize?
Hg
Metals may naturally oxidize and virtually always?
Metals may naturally oxidize and virtually always have the same oxidation number. An oxidation number is assigned to an element in chemical combination that represents the number of electrons lost or gained.
Why do metals oxidize more slowly in air?
they combine with oxygen and form oxides. iron oxidizes into rust (iron III oxide) copper oxidizes, so does aluminum, so do most metals. some metals, such as gold and platinium oxidize to a much lesser extent, keeping them shiny.
What are two metals that tarnish quickley in air?
Silver and copper! both will oxidize noticably.
Name a disadvantage of ferrous metals?
They generally oxidize with exposure to the moisture in air, producing rust.
What elements undergoes rusting?
Most of the metals will oxidize, but the only one for which that process is called "rusting" is iron.
What metal rusts by oxidation?
Many metals will oxidize but only Iron forms rust when doing so.
What type of acid do you need to melt metal?
Acids don't actually melt metal, they oxidize or corrode them. Usually producing the corresponding metal salt and hydrogen gas. Most strong acids (hydrochloric, hydrobromic, hydroiodic, perchloric, nitric, and sulfuric acids) will oxidize metals in this manner. Some weak acids such as hydrofluoric acid can oxidize metals. Some metals, such as the alkali metals and alkaline earth metals will react with virtually any acid and even water. Nitric acid can oxidize copper, which normally doesn't react with acid. Aqua regia, a mixture of nitric acid and hydrochloric acid will oxidize gold and platinum, which are usually considered immune to corrosion.
What block of elements on the periodic table will oxidize or lose elements?
They lose electrons, not elements. These are metals. Group I metals (IA or alkali metals), Group 2 metals (IIA or alkaline earth metals), transition metals (groups 3 thru 12), and all other metals.
Which property of metals make them suitable for use in jewelry?
The most important property of the metals that are suitable for jewellery is that they do not oxidize easily. These metals are at the bottom of the activity series, and they are copper, silver, mercury, platinum, gold.
