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 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 ...

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 ...

The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: This table summarises the reactions of some metals in the ...

👉 Watch the video of Sarah’s science experiment at STEM Academy Nimitz! Hello parents, teachers and students! Wanna see something cool? These soft and shiny metal react dramatically with water. Be ...

For decades, science enthusiasts have delighted at the famously energetic way sodium and potassium explode on contact with water. Researchers in Europe now show that the long-accepted explanation 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 ...
