Superconducting binary hydrides: Theoretical predictions …
WebFor binary alkaline earth and rare earth hydrides, a systematic search for their crystal structures and superconductivity has been accomplished mostly by theoretical prediction, with the exception of few magnetic rare earth hydrides. The binary hydrides potentially with high-temperature superconductivity have attracted great attention for the ... WebCovalent hydrides are primarily compounds of hydrogen and nonmetals, in which the bonds are evidently electron pairs shared by atoms of comparable electronegativities. For example, most nonmetal hydrides are volatile compounds, held together in the condensed state by relatively weak van der Waals intermolecular interactions (see chemical bonding). … WebIt formed ionic hydrides with highly active metals, covalent chemical compounds in which it has an oxidation state of −1 with lesser electronegative elements, and covalent compounds in which it has an oxidation state + 1 with most of the electronegative nonmetals. It reacts dynamically with oxygen, fluorine, and chlorine, is less active with ... cannot resolve symbol theme
