Question

Quizplus · Accepted Answer

Metallic (interstitial) hydrides are formed when hydrogen molecules and atoms occupy holes within the crystal structure of the metal. They do not have distinct stoichiometric formulas like ionic hydrides, nor do they form bonds with the metals by donating their electron to the valence band of the metal. While some metallic hydrides may be useful catalysts, this is not a universal property. Additionally, these hydrides are not stabilized by hydrogen bonding forces.
