Metals react with air in a form called oxidizing. This is caused because the oxygen molecules are reacting with the surface of the metal.
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.
yes, they are less reactive than group 1 and 2. These metals hardly react with air or water at all whereas Group 1 and 2 metals tarnish quickly and react with water
Aluminum, copper, and iron.
When iron reacts with air, they form ferric oxide.
Sodium and lithium are stored in oil so they don't react with air.

group one and two metals react with oxygen in the air as well as moisture to from metal oxides
Oxygen
oxidation
They react (oxidise) with the oxygen in the air.
react with the air, generally oxygen
yes, they are less reactive than group 1 and 2. These metals hardly react with air or water at all whereas Group 1 and 2 metals tarnish quickly and react with water
react with the air, generally oxygen
Yes, both the alkali metals and the alkaline earth metals with react with oxygen. The alkali metals will do so rapidly even at room temperature, cesium and rubidium self-ignite on contact to air.
Aluminum, copper, and iron.
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
When iron reacts with air, they form ferric oxide.
