High melting and boiling points - Ionic bonds are very strong - a lot of energy is needed to break them. So ionic compounds have high melting and boiling points. Conductive when liquid - Ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move. read more
In such cases the ionic compound will conduct and get electrolysed in the process. Now how good a solution of ionic compound will conduct depends on many factors such as temperature and concentration of ions the higher the better the conductivity. Further it will depend on the type of compound. read more
Electrical conductivity requires the movement of charged particles. In the case of electrolytes or liquefied or molten ionic compounds, positively and negatively charged particles are generated and can move around. In metals, positive metal ions are arranged in a rigid lattice or crystal structure that cannot move. read more
