Performing chemical bonding analysis of the Na2He compound, chemists note previously undetected features and predict that, by adding oxygen, a similar compound can be created. Can helium bond with ...

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 ...

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 ...

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 ...

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 ...

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 ...

Scientists have coaxed one of the universe’s most stubborn elements into a new compound. Formed under intense pressures, the newly discovered compound packs helium atoms into crystalline iron, ...

Helium, a noble gas, was long believed to be 'too aloof' to react with the other elements on the periodic table. Now, however, scientists have provided a theoretical explanation of how helium may be ...
