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 ...

There are 118 elements known at present. There are similarities as well as differences are the properties of these elements on the basis of their, all the element can be divided three types: Metal; ...

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 ...

Water is an almost unavoidable element in surface chemistry—in some cases essential, and in others undesirable. The nature of water interactions with metal oxides is a topic of special interest for ...

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 ...

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 ...

A recent study published in Engineering offers new insights into the potential of non-traditional and natural pozzolans (NNPs) as sustainable precursors for alkali-activated binders. The research, ...
