Web25 de jan. de 2024 · Only 0.1 Wm −1 K −1 of heat can be conducted through a typical loose powder bed of metal hydride, and the hydrogenation and dehydrogenation cycles can further pulverize the particles . As a result, the metal hydride bed’s effective thermal conductivity can be further diminished, and as the hydride bed has poor heat transport, … WebThe correct option is C Cr. Cr has tendency to form hydride easily. Elements of group 7,8,9 do not form hydrides thus Cr will only form hydride among the given elements (F e, M n, CO) The low affinity of the elements of the group 6,7.8 and 9 towards hydrogen when in their normal oxidation states prevent the formation of their metal hydrides.

Hydride - Wikipedia
WebWe know metals of group 7,8,9 cannot form hydrides. This is because these metals accept the only negative electron of H atom and the metal ion becomes negatively charged and a ligand is formed in this way.. If the opposite would have occurred, like if the metal lost an electron and became positively charged then the compound formed with hydrogen would … WebSolution. The correct options are. A Palladium. B Chromium. Metals that belong to groups 7,8,9 do not form hydrides. So,this region is referred as hydrogen gap. Since iron and … Web27 de set. de 2024 · Best answer. Correct Answer - A.
