Researchers Forms Stable Compound Na2He of Helium and Sodium

An international team of researchers from China, Russia, and the United States conducted (संचालित) computer modelling to create a thermodynamically stable compound of sodium and the noble gas helium, Na2He, which has a fluorite-type structure and is stable at high High-pressure. The result was

published in the journal Nature Chemistry.  Noble gasses got their name because they were thought not to mix with the other elements and forming no compounds. However, with this experiment, the study of chemistry gets a big change in noble gas theory.

Prof. Boldyrev and his colleagues performed a large-scale computational search for possible stable compounds of helium with a variety of elements (H, O, F, Na, K, Mg, Li, Rb, Cs and so on).

They found that only sodium readily forms a stable compound with helium at pressures accessible(सुलभ)  to static experiments.
