Molecular compounds Ionic compounds
smallest particles molecules cations and anions
origin of bonding electron sharing electron transfer
forces between particles strong bonds between atoms
weak attractions between molecules
strong attractions between anions and cations
strong repulsions between ions of like charge
elements present close on the periodic table widely separated on the periodic table
metallic elements present rarely usually
electrical conductivity poor good, when melted or dissolved
state at room temperature solid, liquid, or gas solid
