Why do ionic compounds tend to have high melting points
« on: March 27, 2006, 09:14:33 PM »
Quick question:

Why do ionic compounds tend to have high melting points?

Also, why do ionic compounds tend to be hard but brittle?

Thanks for the help :)

Think about intermolecular interactions and intramolecular interactions and compare these with respect to ionic and covalent compounds. :)

Agreeing with Mike, a high melting point means strong bonds between the molecules of a compound, or intermolecular bonding.  A stronger bond means it takes more energy, or a higher temperature, to break it and melt.  Therefore, ionic compounds have strong bonds between each of the molecules.
