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 ...

These days talking about bombs will get you locked up or put on an NSA watch list. Back when I was in high school it could be a science fair project. These days you need a college degree to play with ...

Researchers have found a way to create alkali metal hydrides without the use of solvents or catalysts. The process, using room temperature mechanical ball milling, provides a lower cost method to ...

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 ...

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 ...

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 ...

An alkali is derived from the Arabic word 'qali' means ' from the ashes'. As ashes are mixed with water used for cleaning products and are made of alkali materials. It is a basic hydroxide or ionic ...
