When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. This is known as tarnishing. Sodium tarnishes more quickly ...

As a result, aluminum efficiently controlled the existing catalytic electron structure without corrosion, accelerating the oxygen production reaction. Experiments conducted in an alkaline water ...

Aluminum is one of the most abundant metals on earth, bound to other elements like phosphate and sulfate in soil ... foil ...

Metals can react with water, acid and oxygen. The reactivity of the metal ... This produces hydrogen and zinc sulfate, both of which can be tested for. The reactions of metals can be summed ...
