Here’s a popular high school chemistry fact: Helium atoms don’t interact with other atoms to create compounds. Well, that fact might need some reevaluating. An international team of scientists think ...

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 ...

Helium, the second-lightest element in the universe, has a variety of uses, from keeping balloons afloat to cooling superconducting magnets. It is also a noble gas — so labeled because it was long ...

140 years since its discovery, and despite the best endeavors of many scientists, helium, the lightest of the 'noble' gases, still stubbornly refuses to enter into any chemical alliance. Now a new ...

Deep within giant planets, helium may form stable compounds with other elements, a new study finds — something that was long thought never to happen in nature. Helium is second only to hydrogen as the ...

We often wonder what life and environmental conditions would be like on other planets. Scientists have speculated scenarios both similar to what we have on Earth and also completely different from ...

NORTHRIDGE, Calif. and BUFFALO, N.Y. — Helium, the second lightest element in the universe, has a variety of uses, from keeping balloons afloat to cooling superconducting magnets. It is also a noble ...
