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, 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 ...

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 most noble of the noble gases, long thought to be completely inert and thus too standoffish to bond with other atoms, recently surprised chemists by forming chemical compounds after all.

Moscow/Washington, DC -- Although helium is the second most-abundant element (after hydrogen) in the universe, it doesn't play well with others. It is a member of a family of seven elements called 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 ...

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 ...
