A few years ago, a group of physicists created an unusual, never-before-seen subatomic particle. Using a particle accelerator at Riken, a Japanese research institute, they slammed streams of calcium ...

Travel deep enough below Earth's surface or inside the center of the sun, and matter changes on an atomic level. The mounting pressure within stars and planets can cause metals to become nonconducting ...

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 ...

The periodic table captures a subtle pattern that runs through the chemical elements, the fundamental building blocks of everything around us: from the aluminium in bike frames to the xenon gas in ...

The news broke that a railroad car, loaded with pure sodium, had just derailed and was spilling its contents. A television reporter called me for an explanation of why firefighters were not allowed to ...

A new study has revealed the chemical bonding behind sodium's high-pressure transformation from shiny metal to transparent insulator. Travel deep enough below Earth's surface or inside the center of ...

Travel deep enough below Earth’s surface or inside the center of the Sun, and matter changes on an atomic level. The mounting pressure within stars and planets can cause metals to become nonconducting ...
