All metals oxidise. Some are just more resistant than others. Your most reactive are your group 1 metals, Lithium, Sodium, Potassium etc. We keep these in liquid paraffin due to this reason.
Iron oxides quite easily, especially in the presence of water and an acid. Other metals tend to form a protective layer of oxides so only rust on the surface - i.e. Aluminium.
What else can I help you with?
Are most metals dull?
The definition of a metal includes the fact that it is shiny when freshly cut. Metals that readily oxidise would therefore have a dull appearance as a layer of that metal's oxide would quickly form on the outside. Such metals include Zinc, Magnesium and Lead. Any metal that has been left to oxidise for a long time would be dull, so copper or even silver, for example, could also be dull. Unreactive metals are rarely ever dull. Thus Gold and Platinum are examples of metals that are almost never dull.
Do the alkali metals have the ability to tarnish?
By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
What happens when the alkali metals react with chlorine?
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
Which group contains metals that react very quickly with water and air?
The group that contains metals that react very quickly with water and air is the alkali metals, specifically those in Group 1 of the periodic table. This group includes lithium, sodium, potassium, rubidium, cesium, and francium. These metals are highly reactive due to their single valence electron, which they readily lose in reactions with water and oxygen, leading to vigorous and often exothermic reactions.
Why are noble metals difficult to oxidize?
Noble metals are by definition stable and thus in a low energy state. Oxidizing them would put them in a much higher energy state. Nature prefers low energy. That is one reason why water flows down hill. It is flowing to lower energy. So a noble metal is quite happy in that state and is difficult to oxidise. Platinum and gold are two such examples.
Why do metals go rusty?
They react (oxidise) with the oxygen in the air.

What metals silver aluminum copper zinc and steel would be the first to rust?
steel - due to the presence of iron in it. others will oxidise, not rust.
Does metal cool off quickly?
No metals do not cool off quickly.
Do the alkali metals have the ability to tarnish?

Why does metals corrode more quickly near the sea?
Because some metals are reactive and corrode in sea water
Why are metals and minerals a nonrenewale resources?
Because you can't really create metals again, naturally and quickly anyway
What is the process in metals rusting?
This is simple oxidation of the metal: Eg when Iron rusts (such as in nails) Iron + Oxygen ---> Iron Oxide Fe(s) + O2(g) -----> Fe2O3 (s) The reaction is usually quite slow and will cause the metal to corrode Most metals with Oxidise in air, however not all will rust. Aluminium for example is too reactive to corrode, a thin layer of Aluminium oxide forms at the surface that provents the metal below from rusting. Gold on the other hand is inert and with not oxidise readily in air.
What happens to an alkali metals surface as soon as it is scratched?
quickly oxidation
Do heavier metals melt more quickly?
the melting points vary .
Why should window frames not be made out of metal especially near the ocean?
Iron frames tend to corrode. The same is not true of all metals, and aluminium frames work quite well.
What reacts quickly with water and acids?
Reactive metals like sodium, potassium, and magnesium react quickly with water to produce hydrogen gas. Strong acids like hydrochloric acid and sulfuric acid also react quickly with metals to produce metal salts and hydrogen gas.
