Transitional metal hydrides The most fascinating among the three, - TopicsExpress



          

Transitional metal hydrides The most fascinating among the three, their bonding nature vastly differs from element to element and changes according to external criteria such as temperature, pressure and electric current. Titanium and coinage metal hydrides are polymeric. Palladium hydride is not yet clearly considered a compound though it possibly forms Pd2H. The dihydrogen molecule (H2) shares electron with palladium in some yet unknown manner and hides itself within the spaces of the palladium metal crystal structure. Palladium adsorbs up to 900 times its own volume of hydrogen at room temperatures and was therefore once thought as a means to carry hydrogen for vehicle fuel cells. Hydrogen gas is liberated proportional to the applied temperature and pressure but not to the chemical composition.
