Inert gas helium, famous for its reluctance to react with other elements, has produced a very stable new compound called sodium helide. This feat was achieved by subjecting helium to high pressure to ...

Helium, the gas that fills up our balloons, has a reputation as a chemistry lightweight—as an element that doesn’t react with much of anything. Researchers say they’ve used high pressure to coax ...

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 ...

All good research breaks new ground, but rarely does the research unearth truths that challenge the foundation of a science. That's what chemists have now done. Scientists have compressed sodium ...

Noble gases—helium, neon, argon, krypton, xenon, and radon—have long been believed to be the least reactive elements on the periodic table. Helium’s composition in particular, with its full outer ...

Sodium can catch anyone by surprise—even a hypertension specialist like Dr. Jennifer Cluett. Cluett knows all about high blood pressure. She's a practicing primary care physician, an assistant ...
