Metallic Hydrides

Hydrides|| Ionic/Salt-like/Saline Hydride|| Interstitial/Metallic Hydride|| Covalent/Molecular Hydride|| Electron Deficient Hydride|| Electron Precise Hydride||Electron Rich Hydride

Consider the following types of hydrides 1. Covalent hydride 2. Ionic hydride 3. Metallic hydride Which of these are formed by hydrogen?

When an alkali metal is reacted with hydrogen then metallic hydride is formed. In this reaction

Metal hydrides are ionic, covalent or molecular in nature. Among LiH, NaH, KH, RbH, CsH the correct order of increasing ionic character is

Metal hydride on treatment with water gives :
