The Alkali metals represent the 1st group of the Periodic Table and consist of Lithium metal, Sodium metal, Potassium metal, Rubidium metal and Cesium metal. The first 3 alkali metals can be safely stored both under mineral oil or argon. The last 2 alkali metals (Rubidium and Cesium) can be stored only under argon or vacuum condition. The mineral oil prevents but doesn't stops the oxidization of these 3 air-sensitive metals (Lithium, Sodium, Potassium) which over the years inevitably oxidized even if very slowly. The alkali metals sealed under argon, instead, will shiny forever and they will never oxidize, they are protected by argon and they can not react with oxygen of the air. However the production of a shiny sample of Lithium, Sodium, Potassium, Rubidium and Cesium metal is very expensive, therefore the price between the 2 kind of storage are really different.
