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 ...

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 ...

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 ...

A NASA/ESA Hubble Space Telescope image released July 7, 2012, shows U Camelopardalis, a star nearing the end of its life located in the constellation of Camelopardalis (The Giraffe), near the North ...

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 ...

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 ...

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 ...

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 ...
