Because in air potassium is easy oxidized.

∙ 15y agoPotassium, sodium, and lithium all react violently in the presence of water. The hydroxide compounds of all three metals are much more thermodynamically stable than the pure substance. This means that they will release energy (in the form of heat in this case) when they react with the water to form the hydroxide compounds. All three metals will actually ignite and burn under water. The reason they are stored in oil, is because oil and water (or moisture in the air) don't mix.

∙ 12y agosodium and Potassium react vigourously with air which prevents it to be stored outside kerosine.
Potaasium reacts very violently with water producing hydrogen gas which then usually catches fire. Potassium is usually kept under a mineral oil such as kerosene to stop the metal reacting with water vapour present in the air. Unlike lithium and sodium, however, potassium should not be stored under oil indefinitely. If stored longer than 6 months to a year, dangerous shock-sensitive peroxides can form on the metal and under the lid of the container, which can detonate upon opening. It is recommended that potassium, rubidium or caesium not be stored for longer than three months unless stored in an inert (oxygen free) atmosphere, or under vacuum

∙ 7y agoThese elements as pure metals (and lithium as well) react strongly with oxygen in the air, and water, exothermically forming hydroxides. This can cause violent combustion. So the pure metals are stored in oils such as paraffin or kerosene which are not miscible with water, and suspended so that any water contaminant will sink to the bottom of the container and not come in contact with the metals.

∙ 14y agoBecause they are both in a class of compounds called Alkali Metals and are extremely reactive. They will even react with the air, so are stored in oil to prevent oxidation.
The pure metal must be stored under oil to protect it from oxygen and water vapor in the air.
it can b stored in oil
sodium lithium Alkali metals are often stored under oil.
Sodium and Potassium are often store in oils or air sealed containers so they dont react with humidity.
Potassium is a metal.

No. Potassium will react violently on contact with water. Potassium is stored under oil to protect it from air and water.
Potassium is a metal at normal temperatures. It has to be stored under oil otherwise it will react with oxygen in the atmosphere, possibly dangerously.

sodium lithium Alkali metals are often stored under oil.
because they react to oxygen
It oxidizes quickly when exposed to air and reacts violently with water, producing enough heat to burn the hydrogen created in the process.
potassium is a group one metal. Group one metals can be explosively reactive with water (they are very reactive and dangerous) i think tjey woyld be better stored ib oil
as it reacts with the oxygen in the air
Sodium and Potassium are often store in oils or air sealed containers so they dont react with humidity.
