why ionic compounds are good conductor of electricity?
4122
Conduction of electricity Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. ... Ionic compounds are conductors of electricity when molten or in solution, and insulators when solid.

Ionic compounds are named for their positive metal ion first, followed by their negative nonmetal ion. Ionic compounds are solids with high melting and boiling points. They are good conductors of electricity but only when dissolved in water. Their crystals are rigid and brittle.

Which one of the following properties is not generally exhibited by ionic compounds? Solution : Ionic compounds can conduct electricity in molten or aqueous state only. in soiid state, these are non-conductor of electricity because of the absence oi iree ions.

Covalent bonds are formed by sharing of electrons. they don't have a free electron that is required for electricity transfer (electricity is the flow of free electrons!) thus they are bad conductors but ionic compounds are a good conductor because of the presence of free electrons.

Ionic compounds are solids with high melting and boiling points. They are good conductors of electricity but only when dissolved in water. Their crystals are rigid and brittle. Ionic compounds have many uses in industry.

Metals are good conductors of heat. There are two reasons for this: the close packing of the metal ions in the lattice. the delocalised electrons can carry kinetic energy through the lattice.

In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

Ionic crystals are hard, have high melting points, and are brittle. When they melt, the resulting liquids conduct electricity well. These properties reflect the strong attractive forces between ions of opposite charge as well as the repulsions that occur when ions of like charge are placed near each other.

In summary, ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier" - it can be transferred without moving ions too far from their mean positions.

Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Ionic compounds are great conductors of electricity when dissolved or melted. ... Covalent compounds, on the other hand, are almost always good insulators of both electricity and heat. Electricity is not able to conduct efficiently through covalent compounds because there are no ions to move the electrical charge.

Salt itself is not a good conductor of heat but solution of salt in water conducts heat. Salt water is a good conductor because it is an ionic compound. When dissolved, it breaks up into ions. The ions are then good charge carriers, which is what electricity needs.

Ionic compounds are hard and brittle. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not.

Ionic compounds have high melting points. The electrostatic attraction (ionic bond) between cations and anions is strong. It takes a lot of energy to overcome this attraction in order to allow the ions to move more freely and form a liquid. ... The charge on the ions.

The structure and bonding of metals explains their properties : they are electrical conductors because their delocalised electrons carry electrical charge through the metal. they are good conductors of thermal energy because their delocalised electrons transfer energy.

Ionic compounds are electrically neutral because they form ionic bonds between positively and negatively charged atoms.
