Sodium and the other alkali metals are highly unstable, because of that one electron attached to the outer shell of a sodium atom, they will react with almost anything to get rid of that annoyance. So, kerosene, being one of the noble gases and totally inert (meaning highly stable and not able to react with anything expect for a few highly unstable/radioactive elements), is used to seal the sodium from reacting.
Sodium
Sodium is extremely reactive. It oxidizes rapidly in air and reacts violently with water. The kerosene prevents the sodium from coming in contact with air, water, or other substances that might oxidize it.
Sodium metal IS stored in petrol, or more commonly is kerosene or oil.
Because phosphorus is very reactive non metal. It catches fire if exposed to air. To prevent the contact of phosphorus with atmospheric oxygen,it is stored in water. Whereas,sodium is very reactive. It reacts vigorously with oxygen and water. A lot of heat is generated in the reaction. It is, therefore,stored in kerosene
Sodium react vigorously with air, to prevents it's harmfulness it is to be stored under kerosene.

Sodium metal reacts violently with water, and is stored in kerosine (for example) to avoid contact with moisture in the air.
The kerosene prevents the sodium from coming in contact with water and air. Sodium is very reactive. If it touches air it will oxidize, ruining the sample. If it touches water it will burst into flames.
when exposed to air or moisture, sodium will catch fire. to prevent that, sodium is stored in kerosene oil
The kerosene prevents the sodium from coming in contact with air or water. If sodium touches air it will oxidize and ruin the sample. If it touches water it can catch fire and even explode.
Sodium reacts violently with water, and oxidizes rapidly. Containing it in either kerosene or sand (soil) basically protects it from oxidation, and from exploding if water happens to contact it.
as it reacts with the oxygen in the air
