Sodium can be kept in hands because if u go take some salt right now put it in your hands, there is your answer.
sodium must be kept under kerosene
Sodium metal is usually kept under paraffin because of its high reactivity.
It is not necessary; sodium chloride is stable.
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 .
sodium
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.
sodium will react with oxygen and kerosene will have no oxygen molecules in it
Sodium is very reactive and easily react with oxygen or water.
Yes, its kept in mineral oil to prevent oxidation.
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.
