because they react very vigorously with oxygen and moisture and sometimes also cause fire
as if it gets in contact with air it reacts vigorously and burns.
as it reacts with the oxygen in the air
Sodium
Metals such as potassium and sodium react so vigorously that they catch fire if kept in open.Hence,to protect them and to prevent their burning they are stored in kerosene as moisture cannot enter in it.
Sodium metal IS stored in petrol, or more commonly is kerosene or oil.
Sodium react vigorously with air, to prevents it's harmfulness it is to be stored under kerosene.

Because in air potassium is easy oxidized.

sodium, sodium potassium, potassium lithium, lithium aluminum hydride
when exposed to air or moisture, sodium will catch fire. to prevent that, sodium is stored in kerosene oil
Potassium is stored in not aqueous or non-protic solvents such as kerosene or hexane
sodium and potassium are kept under kerosene surface to protect them from rust since the are very active elements and react with O as soon as being exposed to it.
