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 recluse of the periodic table — is reluctant to react with other elements. But squeeze the element hard enough, and it will form a chemical compound with sodium, scientists report. Helium ...

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 ...

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 ...

The inner mantles of icy giant planets such as Uranus and Neptune are mainly composed by water, ammonia and methane, while their atmospheres are made of hydrogen and helium. Under high pressures ...

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 ...

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 ...

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 ...

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 ...
