Sodium is very reactive and easily react with oxygen or water.
Sodium is not placed in air because it is highly reactive and in the air it reacts with air very violently with the oxygen and burns with explosion. Hence it is always kept inside kerosene
When exposed to air or moisture, sodium will catch fire. Hence sodium cannot be kept in bottles on the shelf and generally sodium is kept inserted in non-polar solvents such as kerosene, pentane, hexane etc.
When you cut the likes of sodium or potassium it leaves a shiny surface which will quickly turn dull as they react with Oxygen in the air. To prevent them reacting with any of the air, these elements are usually kept in oil.
Oxygen (which react with sodium) is not dissolved in kerosene.

Sodium is very reactive, it can even react with water or air. So for this reason it is only kept in kerosene
Sodium is kept immersed in Kerosene oil because it's extremely reactive and will react with steam or any other substance. So as to obtain it in its pure form, it's kept in oil. Sodium is very reactive metal and it reacts with any thing that comes into contact with it.It is kept under the oil because it might react with air .
When exposed to air or moisture, sodium will catch fire and explode. So it is kept immersed in an inert or non-polar solvent (such as hexane, pentane) to prevent its contact with air or moisture.

Sodium metal reacts violently with water, and is stored in kerosine (for example) to avoid contact with moisture in the air.
Sodium is metal. It is poisonous substance and also highly reactive. It catches fire when exposed in air.
Sodium metal is kept submerged in light oil distillates so that it doesn't react with the oxygen in the air, as it is a very reactive metal. Pure sodium also reacts violently with water.
When you cut the likes of sodium or potassium it leaves a shiny surface which will quickly turn dull as they react with Oxygen in the air. To prevent them reacting with any of the air, these elements are usually kept in oil.
When left open to air, carbon dioxide will react at the gas-liquid interface. CO2 + 2OH- --> 2HCO3-
because it sublimes in the air. in easier language it dissolved n air easily
Moisture in the air condenses on the cold bottle. If the air is dry, there will be no dew on the bottle.
