Sodium is a silvery white metal belonging to Group1 of the Periodic Table, which is the alkali metals group. Sodium is highly reactive. The pure metal is kept under oil or kerosene because it spontaneously ignites in water. It's interesting to note that sodium metal also floats on water!Room temperature sodium metal is soft enough that you can cut it with a butter knife.

Sodium is kept in kerosene because it keeps it away from contact with air[oxygen].

Sodium is the most reactive element and hence it reacts with water it will burst therefore it stores in kerosene in glass bottles.

Because in water it will burst and also it stores in kerosene in glass bottle.

Sodium is most reactive element hence it reacts vigorous that's why some traces kept in kerosene.

AS sodium is highly reactive, it reacts with oxygen vigorously to form sodium peroxide when exposed to air. Hence it is stored under kerosene.

Because it react with H2O and burned and form H2 vigorously. In air trace amount of water present.

Sodium reacts with air and form following reaction
Na+H2O(IN THE PRESENCE OF O2)=NaOH+H2
So avoid raection with H2o & O2 Na kept in kerosene oil.
Na+H2O(IN THE PRESENCE OF O2)=NaOH+H2
