How do you classify hydrides?

There are three types of hydride: saline, metallic and covalent (there are alternative names for the types of hydride, but these are most common). Saline hydrides have crystalline, salt like structures, and are formed with hydrogen and the group 1 and group 2 metals (the alkali metals and the alkaline earth metals). Metallic hydrides are brittle solids with fairly simple structures, generally formed between hydrogen and the transition metals. They can often have non-integer stoichiometries, e.g. ZrH1.3. Covalent hydrides are formed between hydrogen and the p-block elements, and tend to be gases as room temperature (there are exceptions to this, because of hydrogen bonding).


What is covalent hydrides?

Covalent hydrides are all the other compounds of hydrogen wher hydrogen is covalently bonded- typiccally sharing an electron pair as in CH4 (methane) which could be called carbon tetrahydride although this is not a recognised name.The term hydride is usually applied to ionic compounds of hydrogen and metals of group 1A (alkali metals) and group 2A (alkaline earth metals) (notale exception Be) . In these hydrides,metal atoms form positive ion by losing valence electronsand hydrogen forms negative ion gaining that electron in order to complete its shell.
