Metals react differently. Some are very reactive and others are unreactive. Observations of reactions can be used to put metals into an order of reactivity. For example, copper is unreactive so it can ...

When alkali metals like sodium dissolve in liquid ammonia, they produce a colorful spectacle that has puzzled and delighted chemists for centuries. The metals release electrons that give the solution ...

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 ...
