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.

Can an ionic compound conduct electricity?
Ionic bonds are the electrostatic attraction between positive and negative ions. Ionic solids exist as networks/lattices of oppositely charged ions. Ionic compounds do not conduct electricity in solid state as the ions are not free to move.
Under what conditions could a ionic bond form?
Ionic bonds form when metals and non-metals chemically react. By definition, a metal is relatively stable if it loses electrons to form a complete valence shell and becomes positively charged. Likewise, a non-metal becomes stable by gaining electrons to complete its valence shell and become negatively charged.
Why are ionic compounds electrically conductive?
In short, ionic compounds conduct electricity in water because they separate into charged ions, which are then attracted to the oppositely charged electrode.
How can you tell if a compound will conduct electricity?
The easiest way to determine whether a compound can conduct a current is to identify its molecular structure or composition. Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. These ions can move and carry a current effectively.
Why do ionic compounds not conduct?
Ionic compounds are formed by attraction between the positive and negative ions. These ions cannot move out of their fixed positions. Thus, solid ionic compounds do not conduct electricity.
Why do ionic compounds not conduct electricity as solids?
Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current .
What characterizes an ionic compound?
Ionic compounds have high melting points. Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water. ... An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions.
What are the main properties of ionic compounds?
Properties of Ionic Compounds
Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals.
Can ionic compounds conduct electricity in gaseous state?
One thing is that the ionic compound in gas form will be like neutral molecules hence lose their ability to conduct electricity.
What molecules can conduct electricity?
Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity.
Why do ionic compounds conduct electricity and covalent compounds do not?
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.
What can conduct electric current under certain circumstances?
A substance that will conduct electricity only under certain conditions is called a semiconductor.
Why is an electrolyte able to conduct electricity while a Nonelectrolyte Cannot?
Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity. Nonelectrolytes do not dissociate into ions in solution; nonelectrolyte solutions do not, therefore, conduct electricity.
What determines if something can conduct electricity?
Materials conduct electricity if one of two things happens: If electrons can move around freely (as in the delocalized bonds of metals), then electricity can be conducted. If ions can move around freely, electricity can be conducted.
