Question

Name a metal that is stored in kerosene.

Answer 1

1. Metals react with oxygen easily when left in the open air. On reacting with oxygen, the metal oxide is formed. Such metals are highly reactive.
2. Sodium (Na) and Potassium (K) are the two metals that are highly reactive in nature. It can react with oxygen $\left({\mathrm{O}}_2\right)$ and mositure $\left({\mathrm{H}}_2\mathrm{O}\right)$, and catches fire easily if kept in the open air. To prevent such a reaction, it is not kept in the air and kept in kerosene so that no reaction occurs.
3. Thus, Sodium (Na) is a metal that is stored in kerosene.
