There are two different structures for covalent bonding. When ionic bonding forms between a metal and a non-metal, lots of ions group together to form a giant ionic lattice. A giant ionic lattice ...

Ionic compounds form what is known as a lattice structure. This is a regular arrangement of metal and non-metal ions which creates compounds with very high melting points which conduct when molten ...

The lattice structures of the two materials, and therefore also their quantum mechanically permitted lattice vibrations, are so different that thermal vibrations cannot simply be transferred from ...
