Answer:

Due to their reactivity, alkali metals are always stored in inert solvent such as kerosene oil. And this coating helps them prevent them from coming in contact with air and moisture.

Alkali metals are quite reactive towards air and water, with increasingly dangerous reactivity as one moves down the column from Li to Cs. The reaction with water can be summarized by the chemical equation below where M = an alkali metal.

2 M(s) + 2 H2O ➡️2 M+(aq) + 2 HO-(aq) +H2(g)

The heat generated by this reaction is sufficient in most cases to ignite the hydrogen gas (H2) that is evolved in the reaction. This can result in a powerful explosion depending on the amount and surface area of the alkali metal. Elemental potassium and cesium are particularly dangerous in this regard; even one gram can cause a serious hazard. When working with alkali metals, be sure you have a fire extinguisher that is approved for Class D fires.

Because of their water-reactive and/or pyrophoric nature, alkali metals are usually stored under an inert atmosphere and/or mineral oil.
