why are ionic compounds bad conductors?
349017
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. But all that changes when ionic compounds dissolve in water.

Ionic solids—Made up of positive and negative ions and held together by electrostatic attractions. They're characterized by very high melting points and brittleness and are poor conductors in the solid state.

These ionic bonds between the charged particles result in a giant structure of ions. Because the ions are held together tightly in this giant structure it takes a lot of energy to break all the bonds. As a result, ionic compounds have high melting and boiling points.

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.

Ionic solids are very hard and brittle. Hard due to the strong bonds. Brittle since when distorted like charged ions move closer to each other and the strong electrostatic repulsions shatter the crystal. Ionic solids cannot conduct electricity.

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.

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

The reason why ionic compounds are hard and brittle is because the ions in the compound are already held rigidly in place in a lattice due to the strong electrostatic forces of attraction in between the cations and the anions as well as the repulsion in the ions with like charges .

When solid, ionic compounds do not conduct electricity as the ions are held in fixed positions and cannot move; however, when molten or dissolved in water the lattice breaks down and the ions can move and carry charge. Therefore, ionic compounds can conduct electricity when molten or dissolved in water.

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. Ionic compounds conduct electricity when dissolved in water while covalent compounds typically don't.

Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current . But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.

1 Answer. because 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 re bad conductors.. but ionic compounds are good conductor because of the same reason...

a) Ionic compounds b) Metals c) Water. Ionic compounds in the solid state do not conduct electricity because movement of ions in the solid is not possible due to their rigid structure.

Ionic compounds are compounds whereas metals are elements. Ionic compounds are electrolytes whereas metals are conductors. Ionic compounds are brittle whereas metals are malleable and ductile. Metals are sonorous and are shiny whereas ionic compounds are not.

Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.)

Ionic compounds are formed as the result of the formation of positive and negative ions. Electrons are actually transferred from one atom to another to form rare gas electron structures for each ion. The atom which forms a positive ion loses electrons to the atom which gains electrons to form a negative ion.
