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 a high reactive metal if it is kept it will get burned. Kerosene is the right metal to store it because water is a universal solvent and is used for many purposes, petrol is used in automobiles, alcohol is used for some other purposes so these are not right place to store it.

Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide. This is a strongly exothermic reaction, and lot of heat is generated.

Sodium is highly reactive metal. It reacts with water vapour and as a result of it, a large amount of heat is liberated which can lead to a fatal accident. Sodium does not react with kerosene hence it is kept in kerosene.

AWESOME QUESTION!
When sodium reacts with water it separates the hydrogen from water and starts burning. But kerosene did not contain hydrogen. This is the reason why sodium metal is kept under kerosene.

Sodium is highly reactive metal so it comes in contact with air quickly & burns vigorously to form it's oxide to prevent its reaction with air moisture & co2 it kept in kerosene.

Sodium is a non-polar metal so that it dissolves in polar substance like water as kerosene is non-polar liquid it won't react with kerosene so it is stored in kerosene.

To avoid the reaction with the oxygen present in air because sodium is a reactive metal so it is not safe to keep sodium in atmosphere so better store in kerosene.

Sodium oxidized instantly on exposure to air and reacts violently with water, yielding sodium hydroxide and hydrogen gas. Hence it is preserved under kerosene.
