Sodium does not tarnish in the same way that metals like silver or copper do. However, sodium is highly reactive and easily reacts with moisture or other substances in the air, forming sodium oxide or sodium hydroxide on its surface. This can give the appearance of tarnish, but it is actually a chemical reaction rather than oxidation of the metal itself.

Do alkali metals tarnish?
Lithium, Sodium and potassium are all soft metals which can be cut easily with a knife. This freshly cut piece is a shiny silver color which tarnishes quickly to a dull grey as these metals react with the oxygen and water in air. Sodium tarnishes quicker than Lithium and potassium tarnishes quicker than sodium. Thus, Potassium tarnishes quicker than lithium and not the other way around.

What are the Physical traits of sodium?
At room temperature, sodium metal is so soft that it can be easily cut with a knife. In air, the bright silvery luster of freshly exposed sodium will rapidly tarnish. The density of alkali metals generally increases with increasing atomic number, but sodium is denser than potassium. Source: http://en.wikipedia.org/wiki/Sodium#Characteristics
