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.
