Many metals react with oxygen to form metal oxides. Potassium and sodium are soft metal which are easily cut exposing a shiny surface which changes to dull rapidly. The change from shiny to dull ...

When metals react with oxygen, metal oxides are formed. The speed of the reaction depends on the reactivity of the metal. Watch this video for a practical demonstration of reacting metals with oyxgen.

Nature scientists reveal that there is a new form of oxygen that is found at the surface of the ocean. As we know it, the ...

Greater oxygen coverage prevents organic species from reacting on the oxygen-rich CuO surface (bottom right) and promotes ...
