Question

Name the metal which is kept in kerosene and why.

Answer 1

Sodium is kept in kerosene:-

Sodium($\mathrm{Na}$) is kept in kerosene because:

• The electronic configuration of Sodium($\mathrm{Na}$) is $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^1$.
• Sodium($\mathrm{Na}$) is a highly reactive metal.
• Sodium($\mathrm{Na}$) is so reactive that it easily reacts with oxygen and catches fire.
• Kerosene is a mixture of hydrocarbon which does not allow Sodium ($\mathrm{Na}$) to catch fire when placed inside it as it breaks the interaction of Sodium($\mathrm{Na}$) and air.

Therefore, Sodium($\mathrm{Na}$) is a metal that is kept in kerosene.
