Q

Give examples of crystalline bonding types and their properties

A

Covalent network - strong covalent bonds, high mpt, poor conductors e.g. diamond
Covalent molecular - dispersion, soft, low mpt, poor conductor e.g. ice
Metallic solids - delocalised electrons - sea of electrons, good conductors e.g iron
Ionic solids - lattice structure, poor conductors, water soluble e.g. NaCl
