Yes it does, after being released into the oxygen.

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?
Yes, alkali metals like lithium, sodium, and potassium can tarnish when exposed to air. They react with oxygen and moisture in the air to form oxide layers on the surface, giving them a dull appearance.
Does helium rust or tarnish?
No, helium does not rust or tarnish because it is an inert gas. Inert gases like helium do not readily react with other elements or compounds to form rust or tarnish.
What is to silver as rust is to iron?
Tarnish is to silver as rust is to iron. Tarnish is a layer of corrosion that forms on silver when it reacts with sulfur-containing compounds, while rust is the result of iron reacting with oxygen and moisture.
Do the alkali metals have the ability to tarnish?
By forming their oxides, the alkali metals tarnish very quickly with respect to many other metals.
Is a silver tarnish a physical or chemical change?
It is a chemical change. Oxygen from the air combined chemically with the silver to form silver oxide- that is the tarnish.
What are the word equation for the reaction that causes sodium to tarnish?
The reaction that causes sodium to tarnish is with oxygen in the air: 2Na (sodium) + O2 (oxygen) → 2Na2O (sodium oxide)
Why does sodium tarnish then go dull?
Sodium tarnishes when exposed to air because it reacts with oxygen to form sodium oxide. This tarnish layer can then react with moisture in the air to form sodium hydroxide, which gives it a dull appearance.
Which element is soft solid and reacts readily with oxygen?
Sodium is a soft solid element that reacts readily with oxygen. When exposed to air, sodium forms a tarnish of sodium oxide.
Why is jewelry made of gold and silver not calcium and sodium?
Gold and silver are used in jewelry because they are highly lustrous, do not tarnish, and are relatively easy to work with due to their malleability. Calcium and sodium are not typically used in jewelry because they are highly reactive metals that tarnish easily and are not as aesthetically pleasing.
What metals tarnish quickly in air?
Check out Sodium, Potassium, Phosphorus Magnesium too once you get it started.
Do alkali metals tarnish?
Yes, alkali metals like lithium, sodium, and potassium can tarnish when exposed to air. They react with oxygen and moisture in the air to form oxide layers on the surface, giving them a dull appearance.
Why is sodium not used for cutlery?
Sodium is a highly reactive metal and would react with moisture in the air or food, which could be dangerous. It would also tarnish and corrode quickly due to its reactivity. Therefore, sodium is not suitable for use in cutlery.
What is the appearance of Sodium before and after cutting?
Before cutting, Sodium appears as a shiny, metallic silver-colored solid. After cutting, the surface of Sodium will quickly become dull and tarnish due to its high reactivity with oxygen in the air, forming a white or yellowish oxide layer.
Do pennies tarnish or rust?
Tarnish.
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
Do gold coins change or tarnish?
No, gold does not tarnish.
What will happen if you rub ketchup on a tarnish penny and wash it off with water?
i think the tarnish will come of the tarnish penny
