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 is ...

Figure 1: Electronic structures of Co-containing perovskite oxides. Figure 2: Direct evidence of lattice oxygen oxidation involved in the OER of 18 O-labelled perovskites. Figure 3: pH-dependent OER ...

The spectacular reaction of alkali metals with water was poorly understood — despite being a staple of chemistry classes. It’s the classic piece of chemical tomfoolery: take a lump of sodium or ...

When a chunk of alkali metal gets tossed into water, it explodes. But when a team of scientists gently placed a liquid drop of a sodium-potassium alloy on top of a water surface, they observed a ...

Scientists have discovered that physically confined spaces can make for more efficient chemical reactions. Physically confined spaces can make for more efficient chemical reactions, according to ...

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.

It’s the classic piece of chemical tomfoolery: take a lump of sodium or potassium metal, toss it into water and watch the explosion. Although this piece of pyrotechnics has amazed generations of ...
