WebSep 9, 2024 · The general equation for this reaction is: metal + oxygen → metal oxide. How do alkali earth metals react with oxygen? The alkali metals on exposure to air or oxygen burn vigorously, forming oxides on the surface of the metals. Lithium forms monoxide (Li2O), sodium forms the peroxide (Na2O2) and the other elements form super-oxides. WebApr 8, 2024 · Generally, alkali metals and alkaline metals show high reactivity and react with dilute acids, oxygen and water. Let us see some examples of reactions with metals. Reaction of Metals with Oxygen. Oxygen is a strong reactive non-metal and a powerful oxidising agent. Most of the metals react with oxygen and form metal oxide.
