hydrogen bonding exists in compounds having partially positively charged hydrogen and highly electronegative atoms bearing partial -ve charge. such intermolecular forces of attraction infleuence the physical properties like melting and boilingg points. the greater the size of atoms the greater the polarazability hence the greater the boiling points for example: the hydrides of fourth period show greater boiling point than those of third period due to ggreater size and greater polarizability.

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.
Uses of covalent and ionic hydride?
ionic hydrides are source of producind hydrogen and as reducing agents in metallurgical processes and as dehydrating agents for organic solvents.covalent hydrides forms colourless gases,volatile liquids or solids.
Definition of uses of covalent and ionic hydride?
i only got uses of ionic hydrides her it is: Ionic hydrides and their complexes are used as reducing agents. They evolve hydrogen when heated. Hence they are used as solid fuels as they ignite spontaneously. (source: WWW.tutorvista.com)
Why beryllium and magnesium form polymeric hydride?
Because the electronegativities values of Be and Mg are high in comparission of other elements of the group. These two metals form poler covalent bond with hydrogen and due to polarity the units of these hydrides are linked to gather in the form of chain by hydrogen bond. so thier hydrides are called polymeric hydrides.
What is the smallest particle of a covalent compound that shows the properties of that compound?
The smallest particle of a covalent compound that shows the properties of that compound is a molecule.

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 two physical properties are shared by all forms of matter?
Mass and thermodynamic temperature.
What is the smallest particle of a covalent compound that shows the properties of a compound?
The smallest particle of a covalent compound that shows the properties of that compound is a molecule.
What are complex hydrides?
Complex metal hydrides are hydrides containing in the molecule two cations - as LiAlH4.
What is the smallest particle of a covalent compound that shows the properties of that compound?
The smallest particle of a covalent compound that shows the properties of that compound is a molecule.
