Substance Type Bond Type Solid Molten/Liquid Aqueous
Ionic Compounds Ionic Bad (ions fixed in lattice) Good (ions are mobile) Good (ions are mobile and dissociated)
Metals Metallic Excellent (delocalized electrons) Excellent (delocalized electrons remain mobile) Insoluble
Covalent Compounds (Molecular) Covalent Very poor (electrons localized in bonds) Very poor (electrons remain localized) Generally poor (molecules don’t dissociate into ions easily)
Network Covalent Solids Covalent (extended network) Depends Depends(if it can break down) Insoluble
