This is …
WebThe reactivity of metals can differ a lot: Sodium reacts very fast with oxygen. Magnesium a bit more slowly. Aluminium does react with oxygen, but the reaction only affects the surface. The oxide layer protects the rest of the metal. Iron reacts more slowly than aluminium, but the reaction keeps going deeper until the entire object is destroyed. WebMar 21, 2024 · The metal oxides are formed when they react with the atmospheric oxygen. However the reactivities of the different metals towards the oxygen atom vary. Characteristics of the reactivity series of metals: 1.The metals at the top of the reactivity series are most reactive and they are powerful reducing agents.
WebNov 20, 2024 · Rusting is the corrosion of iron. It is the most common corrosion of metal around. For iron to rust, oxygen and water must be present.
