Formation of Lithium Oxide

4Li + O2 → 2Li2O

Aperçu

Lithium metal reacts with oxygen to form lithium oxide. Unlike the heavier alkali metals, lithium primarily forms the normal oxide rather than the peroxide or superoxide. This reaction occurs readily at room temperature, causing lithium to tarnish in air.

Exemple du quotidien

Lithium batteries can react violently if the lithium metal inside is exposed to air, partially due to this oxidation reaction.

Importance industrielle

Lithium oxide is used in ceramics, glass manufacturing, and as a flux. Understanding lithium oxidation is crucial for lithium battery safety and recycling.
