HELIUM COMPOUND Scientists created a chemical compound of helium and sodium by squeezing the elements to extremely high pressures. Helium atoms (green cubes) are arranged in a 3-D checkerboard ...

Everyone's excited about a compound formed with helium, one of the periodic table's most inert elements. But this work has been under scrutiny for three years, and not everyone's convinced.

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 ...

To make the new iron compound, physicist Kei Hirose of the University of Tokyo and his colleagues squeezed iron and helium together in a diamond anvil cell, a high-pressure device that subjected ...

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. Skip to main content.

However, there are tantalizing clues that helium compounds could exist in some volcanic rocks on Earth’s surface. These rocks contain unusually high isotopic ratios of helium-3 to helium-4. “Unlike ...

IT has been shown by Paneth and his co-workers in Berlin that any element which stands in the periodic table from one to four places before a noble gas will form an easily volatile hydride; such ...

It is possible under certain conditions, for example in outer space, for helium and other noble gases to become part of compounds.A stable helium compound was created a few years ago, but only ...
