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 ...

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 ...

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 ...

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 ...

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 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 ...
