Answer» Solution :IONIC (Saline) Hydrides: These are hydrides composed of an electropositive metal, generally, an alkali or alkaline-earth metal, except beryllium and magnesium, formed by transferring of electrons from metal to hydrogen atoms. They can be PREPARED by the REACTION of ELEMENTS at about `400^(@)C`. Theseare salt-like, high-melting, WHITE, crystalline solids having hydride ions `(H^-)` and metal cations `(Mn^+)` `2Li(s)+H_2(g)to2LiH(s)` `2Ca(s)+H_2(g)to2CaH_2(s)` |
