What is a discoloration of metal by exposure to air?
Oxidation is the usual cause of discoloration when an iron is exposed to air. The atoms on the surface of the metal react with Oxygen in air to produce a metal oxide.
When metals react with air to form metal oxide?
All of them except Gold.many form a metal oxide layer that protects them from further oxidization.
How do halogens react with air?
they react in air by oxidising.
Why metal have a lustrous appearance when polished?
metal react to the molecules in the air and they break down the outer layers of the metals into other compounds. polishing the outer layer breaks up those compounds.
What happens when metals react with air water and acids?
Do you mean seperately?If yes, then:When they react with air, it is combustion: 2Ca + O2 --> 2CaOWith water, they simply come to be hydroxides: Na + H2O --> NaOH + H2When they react with acids then a salt and hydrogen gas is formed: Zn +2HCl --> ZnCl2 + H2
What do metals react with that is found in the air?
group one and two metals react with oxygen in the air as well as moisture to from metal oxides
What is a discoloration of metal by exposure to air?

What happens when metal react with air?
I'm behind you Alexander. watching you.
What happens when transition metals react with the air?
Metals react with air in a form called oxidizing. This is caused because the oxygen molecules are reacting with the surface of the metal.
What happen when non metal react with air?
I'm behind you Alexander. watching you.
What metal is used in the reaction of metal and air?
Metals in the reactivity series from aluminium to copper react with oxygen in the air to form the metal oxide. Aluminium and Zinc reacts very quickly, Iron reacts slowly at room temperature. Tin, Lead and Copper reacts with Oxygen in air when heated. Silver, Gold and Platinum do not react with Oxygen in air
When metals react with air to form metal oxide?
All of them except Gold.many form a metal oxide layer that protects them from further oxidization.
Why do metal react with non metal?
Sulfur doesn't react with water.
What are misconceptions about metal?
that all are hardthat all are solid at room temperaturethat all react slowly with air
When metal react with metal the result is?
No change.
Why do metals have to be sandpapered?
The reason why metal have to be clean with sandpaper is to remove the oxide layer on the surface of the metal. This is because most metal have a high tendency toward oxygen. The metal will react with oxygen in the air and form an oxide layer on the surface of the metal.
How do halogens react with air?
they react in air by oxidising.
