How do the structures of ionic and covalent compounds differ?

Question

topic how it is different and cool

 

Answer 1

Ionic compounds tend to have a crystalline lattice structure and as such have relatively high melting points.  Covalent compounds can also exist in lattice structures (such as sucrose), but the forces holding them together are weaker than in ionic compounds.  Ionic compounds form when a cation and an anion are attracted because of donation and acceptance of electrons.  Covalent compounds are formed by a sharing of electrons, and the main intermolecular force is dispersion forces and in some cases dipoles, and hydrogen bonding.
