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 are complex hydrides?
Complex metal hydrides are hydrides containing in the molecule two cations - as LiAlH4.
When alkali metals are heated with hydrongen they form?
we call them hydrides. Hydrides are forming by the reaction.
Why are the elements of group 6 called hydrides?
They aren't particularly or uniquely called hydrides; a hydride is a negative hydrogen ion, H-. Metals can form metal-hydrides, though, including those four elements.
When alkali metals are heated with hydrogen they form?
They form alkali metal hydrides. such as LiH and NaH.
Can you classify everything?
no u cant classify everything

What are the differences between Ionic Hydrides and Covalent hydrides?
Ionic hydrides are formed by the reaction of hydrogen gas with the most electropositive metals. (group 1 and 2 excluding Be and Mg) The reaction involves the forming of a crystal lattice (solid). Covalent hydrides are formed by weakly electropositive metals and are primarily gasses at room temperature.
Why ionic hydrides are called true hydrides?
The ionic hydrides contain H- ions. Some people like the -ide sufffix to refer exclusivelly to ionic species.
Why are Alkai and Alkaline earth metal hydrides are called true hydrides?
because aklai are soluble in water with compltely and alkai earth metal are partially dissolve in water thats they are called true hydrides
Why is BiH3 the strongest reducing agent amongest the hydrides of group 15 elements?
as bih3 is the most unstable hydride in group 15 therefore it is highly reducing
Why are the elements of group 6 called hydrides?
They aren't particularly or uniquely called hydrides; a hydride is a negative hydrogen ion, H-. Metals can form metal-hydrides, though, including those four elements.
Why lithium hydride is more stable than other alkali hydrides?
Lithium hydride is more stable than other alkali hydrides because lithium is both lighter and harder than other alkali hydrides.
When the sign of hydrogen is negative?
In hydrides.
In what two groups does hydrogen form ionic compounds?
Acids and Hydrides? Not 100% sure about Acids, i do know that Hydrides are right though.
Acid and metal produces?
metal hydrides
Which substances have a negative hydrogen?
all hydrides
