why do ionic compounds tend to conduct electricity when they melt?
483341
Ionic compounds cannot conduct electricity in the solid state because their ions are held in fixed positions and cannot move. Ionic compounds conduct electricity when melted or in solution. They are insulators when solid.
967379
Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature.

Solid ionic compounds are poor conductors of electricity. The strong bonds between their oppositely charged ions lock them into place in the crystal. Therefore, the charged particles cannot move freely and carry electric current, which is a flow of charge. ... The ions can move freely, so they can carry current.

The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound (Figure 6.2. 1) .

It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. But some are higher than others. The greater the charge on the ions, the stronger the forces holding them together.

Ionic compounds tend to have higher melting and boiling points than covalent compounds. Ionic compounds tend to be hard and brittle while covalent compounds tend to be softer and more flexible. ... This is because covalent compounds dissolve into molecules while ionic compounds dissolve into ions, which can conduct charge.

Some of the properties of ionic solids are high melting point, low vapor pressure, brittleness and the inability to conduct electricity. Ionic compounds can be readily dissolved by polar molecules like water.

In short, ionic compounds conduct electricity in water because they separate into charged ions, which are then attracted to the oppositely charged electrode.

Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature. ... all remaining forces are overcome during boiling.

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.

Although solid ionic compounds do not conduct electricity because there are no free mobile ions or electrons, ionic compounds dissolved in water make an electrically conductive solution. In contrast, covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

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 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.
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.

A substance with metallic bonds can conduct electricity because electrons can move freely between metal atoms. Ionic compounds consist of strongly bonded ions and therefore have high melting points. ... This makes it possible for many different compounds to form.

Ionic compounds have an equal number of positive and negative ions arranged in the three-dimensional lattice due to which they have high melting points. The strong force of attraction between oppositely charged ions means that ionic compounds have high melting and boiling points.
