Many of us gained our first appreciation for chemistry upon witnessing a high school teacher drop a chunk of sodium into a beakerful of water. You may think you know the explanation behind the ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue investigates chemical reactions involving sodium. Find out how the electron configuration of ...

Click the play button on the video above, and you’ll see a piece of sodium leaping over and over to get its (metaphoric) toes out of the water. It looks like a cute little experiment — but it’s not ...

Chemical reactions make new chemicals. Atoms are rearranged during a chemical reaction, but the number of atoms does not change. Evidence of chemical reactions includes a large temperature change, ...

As the world moves toward cleaner energy and electric technologies, better batteries are becoming more important than ever. Batteries power everything from phones and laptops to electric vehicles and ...

An acid and alkali will neutralise each other and produce a salt and water. This is called a neutralisation reaction. The name of the salt produced can be worked out from the names of the acid and the ...

Electric vehicles are colliding with a hard reality: lithium is expensive, supply chains are fragile, and safety concerns still unsettle buyers. A new generation of solid-state sodium-ion batteries ...

Researchers at Tokyo University of Science showed that sodium-ion batteries with hard carbon anodes can charge faster than lithium-ion batteries by using a diluted electrode method that reveals sodium ...

With the world’s reserves of light oil diminishing, oil companies are increasingly turning to heavier varieties – which make up 70% of global oil reserves – to meet rising energy demands. Existing ...

Sodium-ion batteries (SIBs) are emerging as a sustainable alternative to lithium-ion batteries, thanks to sodium’s abundance and low cost, but their true charging speed remains uncertain due to ...
