Formation of Lithium Oxide

4Li + O2 → 2Li2O

Visão geral

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.

Exemplo do cotidiano

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

Importância industrial

O óxido de lítio é utilizado em cerâmicas, fabrico de vidro e como fundente. Compreender a reatividade do lítio com o oxigénio é importante para o manuseamento seguro e para o desenvolvimento de baterias de lítio-ar.
