... of electricity in the solid and liquid states. When dissolved in water some covalent molecular substances conduct electricity. These substances form or break up into ions (ionise) when added to water. The mobile ions in the aqueous solutions are then able to act as the charge carriers of the electric current. The solubility properties of covalent molecular compounds vary considerably. Some ... electrons. The valence electrons are said to be delocalised as they are not associated with a particular metal ion but can move freely through the lattice of metal ions. The positively charged meta...
