Formation of Lithium Oxide
4Li + O2 → 2Li2O
概要
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.

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