Answer:

Hydrogen forms binary hydrides with

many electropositive elements including

metals and non-metals. It also forms ternary

hydrides with two metals. E.g., LiBH4

and

LiAlH4

. The hydrides are classified as ionic,

covalent and metallic hydrides according

to the nature of bonding. Hydrides formed

with elements having lower electronegativity

than hydrogen are often ionic, whereas with

elements having higher electronegativity

than hydrogen form covalent hydrides.

Ionic (Saline) hydrides: These are

hydrides composed of an electropositive

metal, generally, an alkali or alkaline-earth

metal, except beryllium and magnesium,

formed by transfer of electrons from metal

to hydrogen atoms. They can be prepared

by the reaction of elements at about 400°

C. These are salt-like, high-melting, white

crystalline solids having hydride ions (H−)

and metal cations (Mn+).
