All of the 1st group metals (Li, Na, K, Rb, Cs, Fr) because they react with the air and many other things.
Sodium, Potassium, Rubidium and Cesium are so reactive they are stored under the surface of oil.
rubidium
Group 1 metals are stored under a layer of oil. This prevents them from coming into contact with the oxygen in the air. Thus the violent reaction of group 1 metals and oxygen is prevented and the metals can be stored safely under oil.
cooking oil and gasoline
group 1 metals are stored under oil because they are so reactive, they will react with the oxygen and water in the air if you leave them unprotected, keeping them under oil prevents this from happening, as water and oxygen can't pass through the oil and get to the metal. . .hope this helped pall =].
Sodium and lithium are stored in oil so they don't react with air.
Alkali meatls are stored in oil to stop it from mixing with the moisture in the air.Because Alkali metals are highly flammble in moist air.

They are so reactive they even react with the moisture in the air. Storing under oil prevents this.

To avoid any reactions with oxygen, water, carbon dioxide.
Sodium and lithium are stored in oil so they don't react with air.

They burn in atmospheric air, such metals are stored in oil under dry nitrogen gas.
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.
sodium lithium Alkali metals are often stored under oil.
They are submerged in kerosene or other oil solutions to prevent them from reacting with the water vapor in the air and combusting.
